Some Notes on these STEVENS Operating
Instructions
The picture on the front page of the STEVENS operating instructions shows a
typical STEVENS mountain bike. This bicycle corresponds to the STEVENS bicycle
you purchased. Today’s bicycles come in various types that are designed for spe-
cific uses and equipped accordingly. The STEVENS operating instructions include
the following bicycle types:
Mountain bikes
Kids’ / Junior bicycles
Cross bikes
Gravel bikes
Tandem bicycles
Pay particular attention to the following symbols:
Danger:
This symbol indicates an imminent risk to your life or health unless you
comply with the instructions given or take preventive measures.
Caution:
This symbol warns you of wrongdoings which may result in damage to
property and environment.
Note:
This symbol provides you with information about how to handle the prod-
uct or refers to a passage in the operating instructions that deserves your
special attention.
The described possible consequences will not be repeated in the STEVENS
operating instructions every time one of the symbols appears. These operating
instructions are not intended to help you assemble a STEVENS bicycle from indi-
vidual components, to repair it or to make a partly assembled bicycle ready-for-
use.
These STEVENS operating instructions are not applicable to any other than the
displayed bicycle types.
General Safety Instructions
Dear STEVENS customer,
In purchasing this STEVENS bicycle you have chosen a product of high quality
and technology. Each component of your new STEVENS bicycle has been designed,
manufactured and assembled with great care and expertise. Your STEVENS dealer
gave the bicycle its final assembly and adjustment to guarantee proper operation
and many enjoyable riding experiences with complete peace of mind from the
very first metres.
This manual contains a wealth of information on the proper use of your
STEVENS bicycle and a lot of interesting facts about bicycle technology, mainte-
nance and care. Read these STEVENS operating instructions thoroughly. We are
sure that even if you have been cycling all your life you will find useful and detailed
information. Bicycle technology has developed at a rapid pace during recent years.
Therefore, before setting off on your new STEVENS bicycle, be sure to read at
least the chapter “Before Your FIRST Ride”.
To ensure as much fun and safety as possible during cycling, be sure to carry
out the functional check described in the chapter “Before EVERY Ride” before
setting off on your STEVENS bicycle.
Even a manual as big as an encyclopaedia could not describe any possible com-
bination of bicycle models and components or parts on the market. The STEVENS
operating instructions therefore focus on your newly purchased STEVENS bicycle
and standard components and provides useful information and warnings.
When doing any adjusting and maintenance work, be aware that the detailed
instructions provided in your manual only refer to this STEVENS bicycle.
The information included here is not applicable to any other bicycle type. As
bicycles come in a wide variety of designs with frequent model changes, the rou-
tines described may require complementary information. Be sure to also observe
the instructions of the component manufacturers.
Be aware that these STEVENS operating instructions may require further
explanation, depending on the experience and/or skills of the person doing the
work. For some jobs you may require additional (special) tools or supplementary
instructions. This manual cannot teach you the skills of a bicycle mechanic.
Caution:
If you have purchased
a STEVENS e-bike/
EPAC, be sure to read
the supplied translation
of the original STEVENS
operating instructions.
There you will find
further categories.

Before you set off, let us point out a few things that are very important to every
cyclist: Never ride without a properly adjusted helmet and without glasses and take
care to always wear suitable, bright clothing. At least you should wear straight cut
trousers or leg bands and sturdy shoes fitting the pedal system. Always ride care-
fully on public roads and observe the traffic rules so as not to endanger yourself
or others.
This manual cannot teach you how to ride. Be aware that cycling is a poten-
tially dangerous activity that requires the rider to stay in control of his or her
STEVENS bicycle at all times.
Like any sport, cycling involves the risk of injury and damage. Keep this in
mind. When you decide to ride a STEVENS bicycle you need to accept the risk
inherent to cycling. Note that on a STEVENS bicycle you have no protection tech-
nology around you (e.g. bodywork, ABS or air bag) like you have in a car. Therefore,
always ride carefully and do respect the other traffic participants.
Never ride under the influence of drugs, medication, alcohol or when you are
tired. Be sure to never ride with a second person on your STEVENS bicycle (except
on a STEVENS tandem) and always ride with your hands on the handlebar.
Observe the legal regulations concerning off-road cycling. These regulations
may differ in each country. Respect nature when riding through the forest and in
the open countryside. Ride on signposted, well maintained trails and hard-surface
roads only.
If you bought a STEVENS kids’ bicycle, observe the tips before your child sets
off on it for the first time. In some countries there are specific regulations for chil-
dren. Read the chapter “Kids’ and Junior Bicycles”, before your child uses the
STEVENS bicycle for the first time.
First we would like to familiarise you with the various components used on
your STEVENS bicycle. On the front page of the STEVENS operating instructions
you find an exemplary, typical STEVENS mountain bike showing all the essential
components.
You find all STEVENS user manuals, the instructions of the
component manufacturers as well as detailed information

in the operating instructions or on the websites of the respective component
manufacturers.
Category 5: STEVENS cross-country, marathon and touring mountain bikes
This category describes STEVENS cross-country, marathon and touring
mountain bikes. STEVENS hardtail mountain bikes and full suspension STEVENS
bikes with short suspension travel are typical for this category. STEVENS Mara-
thon, XCCarbon, XCAlloy and Junior Sport.
STEVENS cross-country, marathon and touring mountain bikes are suit-
able for off-road use, but not for blocked terrain, tricks, stair riding etc., training
and competitive use in the categories freeride, dirt, downhill. STEVENS bikes of
this category can be used on surfaces permitted for bikes of the categories 1 and
3 and are in addition suitable for rough and unpaved terrains. Sporadic jumps are
also included in the field of use of these STEVENS bikes. But particularly inexpe-
rienced riders doing jumps may land inappropriately, thus increasing the acting
forces significantly which may result in damage and injuries. We recommend that
you train your skills in a riding technique course. If necessary, ask your STEVENS
dealer to inspect your STEVENS bicycle at shorter intervals than according to the
service and maintenance schedule.
• On full suspension STEVENS mountain bikes made of aluminium the use of
trailers is permitted. On full suspension STEVENS mountain bikes made of
carbon trailers are, however, not permitted.

STEVENS enduro and all mountain bikes are designed for off-road use (Alp-
cross etc.). STEVENS bikes of this category can be used on surfaces permitted for
bikes of the categories 1, 3, 4 and 5. Furthermore, STEVENS bikes of this category
are suitable for very rough and partly blocked terrain with steeper slopes and
higher speeds as a result thereof. On official tracks regular jumps by experienced
riders up to a height of 1.2m are not a problem for these STEVENS bikes. The
regular and durable use of these STEVENS bikes in bike parks, must however be
excluded by STEVENS. In addition, these STEVENS bikes are not suitable for tricks,
stair riding etc. as well as training and competitive use in the categories freeride,
dirt, downhill.

S - 14 | English English | S - 15
Danger:
Due to the higher loads,
STEVENS bikes of the
category 7 should be
checked for possible
damage after every ride.
Three inspections per
year at least carried out
by your STEVENS dealer
are obligatory.
Danger:
Bicycles of the category
8 are not suitable for
off-road use, jumps,
slides, stair riding,
stoppies, wheelies,
tricks etc.!
Category 7: STEVENS dirt and freeride bikes
This category describes STEVENS dirt and freeride bikes. Hardtail frames
with special strengthenings and designated dirt forks are typical for STEVENS
dirt bikes. Full suspension bikes with very long suspension travels are typical for
STEVENS freeride bikes.
STEVENS dirt bikes are intended for harder use on secured terrain. There are
different types of dirt bikes which are either designed for tricks and show rides,
jumps and freestyle in special obstacle parks, whereas others are intended for
races. STEVENS bikes of this category are intended for very challenging, highly
blocked and extremely steep terrains, which can only be mastered by well-trained
riders with technical skills. Rather high jumps at very high speeds as well as the
intensive use of specific, identified bike parks or downhill trails are typical for this
category. With these STEVENS bikes it is imperative to carry out a thorough check
for possible damage after every ride. Preliminary damage with clearly inferior fur-
ther stress can result in failure. A regular replacement of safety-relevant com-
ponents must also be taken into account. Wearing special protectors is strongly
recommended.
STEVENS freeride bikes are suitable for jumps and drops in most challenging
terrains and in bike parks. Full suspension bikes with very long suspension travels
are typical for this category.
• On full suspension STEVENS mountain bikes made of aluminium the use of
trailers is permitted. On full suspension STEVENS mountain bikes made of
carbon trailers are, however, not permitted.
• On full suspension STEVENS mountain bikes child seats are not permitted.
For more information see the chapter “Use of Child Seats”.
Category 8: STEVENS tandem bicycles
This category describes STEVENS tandems. STEVENS tandem.
STEVENS tandems are designed to be used by 1 or 2 riders. They can be
used e.g. for off-road cycling on gravel field and forest tracks, however, not for
rough terrain. They are not suitable for off-road use (mountain bike use), namely
for all mountain, enduro, downhill (DH), freeride, dual slalom, downhill/freeride
parks, jumps, drops etc.
• Due to their design and equipment, STEVENS tandems are not always suita-
ble for being used on public roads. If you want to use them on public roads,
these bikes must be equipped with the prescribed equipment. Observe the
traffic rules when riding on public roads. For more information see the chapter
“Legal Requirements for Riding on Public Roads”.
• The maximum permissible overall weight (rider incl. luggage and bicycle)
should not exceed 210kg. Under certain circumstances this maximum per-
missible overall weight can be further limited by the component manufactur-
ers’ recommendations for use.
• On STEVENS tandems (kids’) trailers and child seats are not permitted.
S - 16 | English English | S - 17
When using a trailer, observe the following points:
• The trailer with its actual weight incl. cargo is considered to be part of the
permissible weight of your STEVENS bicycle. For more information see the
chapter “Maximum Permissible Overall Weight”.
• Be sure to fix the trailer coupling exclusively to the rear axle or to specific
mounts at the drop-out.
Danger:
With some trailer models it is necessary to replace the original thru axle by
a specific thru axle of the trailer manufacturer or to clamp an adapter with
the original thru axle. In this case, make sure that the axle thread and the
axle nut thread are fully covered.
The possibly required replacement axles must comply with the specifica-
tions of the original axle of your STEVENS bicycle (clamping width, thread
pitch and thread length, material and diameter).
Danger:
Always secure the chil-
dren with the seat belt,
uncontrolled movements
inside the trailer can
make your STEVENS
bicycle or the trailer tilt.
Danger:
Make sure that your
child always wears a
suitable helmet. A trailer
is only an insufficient
protection in case of an
accident. Keep in mind
that you always wear a
helmet, as well.
Danger:
Persons must only be
transported in trailers
approved for this pur-
pose.
Note:
You find all STEVENS user manuals, the instructions
of the component manufacturers as well as the
respective weblinks at
www.stevensbikes.de/manual
Danger:
Attaching the trailer
coupling to the frame
tubes, rear stays or seat
post is not permitted.
Danger:
If the lighting equipment on your STEVENS bicycle is covered by the trailer,
it has to be mounted visibly to the trailer. When riding in the dark, provide
the rear end of the trailer with a battery/accumulator-operated lamp.
Danger:
Trailers affect the braking behaviour and the width of your STEVENS bicy-
cle. First, practise riding with an empty trailer. Equip the trailer with a long
pole with coloured pennant to increase visibility.
Danger:
Keep in mind that
your stopping distance
increases with the
additional load due to
the transport of children
and cargo.
Maximum Permissible Overall Weight
The maximum permissible overall weight is indicated on the category sticker
on your STEVENS bicycle.
The maximum permissible overall weight limit is made up as follows:
Weight cyclist (kg)
+ Weight bicycle (kg)

When taking your child with you in a child seat, observe the following points:
• Always put a fitting helmet on your child and this already before you place him/
she in the child seat. Many accidents happen when the bicycle is stationary,
e.g. when it tips over. Be a good example and remember to always wear a
helmet yourself.
• Never set off before having buckled up your child in the child seat. Uncontrolled
movements of the child can make your STEVENS bicycle tilt.
• Do not overload your child seat. Overloading can result in breakage of the
frame, the fork or the components. Risk of accident and injury!
• Cover the springs of your saddle to make sure that your child will not have the
fingers pinched.
• Adjust the tyre pressure to the additional weight. The maximum pressure is
indicated on the tyre side
Danger:
Child seats mounted with a suitable adapter for pannier racks/luggage
carriers are only permitted, when the pannier rack complies with the
requirements of ISO11243 and has a maximum payload of at least 25kg.
Danger:
Child seats are only permitted on STEVENS bikes, when indicated in the
bike card.
Danger:
Child seats that are
mounted to the seat
tube are the only child
seats permitted. Child
seats that are mount-
ed to the seat post or
the top tube are not
permitted.
Danger:
Be sure to only use
child seats which are
mounted in the rear with
the child sitting behind
the rider. Child seats
that are mounted in
front of the rider are not
permitted.
Danger:
When mounting a child
seat, observe the maxi-
mum permissible overall

Before Your First Ride
1. If you want to use your bicycle on public roads, it has to comply with the
respective legal requirements. These regulations differ from country to coun-
try. Therefore, bicycles are not necessarily equipped completely. Ask your
STEVENS dealer for the laws and regulations applicable in your country or in
the country where you intend to use the STEVENS bicycle. Have your STEVENS
bicycle equipped accordingly, before using it on public roads.
2. Are you familiar with the brake system? Have a look at the bike card and check
whether the brake lever of the front brake is on the side you are used to (right
or left). If it is not, ask your STEVENS dealer to switch the brake levers before
you set off for the first time.
Your new bicycle is equipped with modern brakes which may be far more
powerful than those you were used to so far. Be sure to first practise using the
brakes on a level, non-slip surface off public roads!
For more information see the chapter “The Brake System” further below as
well as the instructions of the component manufacturers.
3. Are you familiar with the type and functioning of the gears? Ask your STEVENS
dealer to explain to you the gear system and make yourself familiar with your
new gears in an area free of traffic, if necessary.
For more information see the chapter “The Gears” further below as well as
the instructions of the component manufacturers.
4. Are both the saddle and the handlebar properly adjusted? The saddle should
be set to a height from which you can just reach the pedal in its lowest position
with your heel. Check whether your toes reach to the floor when you are sitting
on the saddle.
For more information see the chapter “Adjusting the STEVENS Bicycle to
the Rider” further below as well as the instructions of the component manu-
facturers.
Danger:
Be aware that the
distance you need to
stop increases, when
you are riding with your
hands on bar ends. The
brake levers are not in
all grip positions within
easy reach.
5. If your STEVENS bicycle is equipped with clipless or step-in pedals: Have you
ever tried the shoes they go with? Do not set off until you have practised
engaging and disengaging the shoes from the pedals while stationary. Ask your
STEVENS dealer to explain to you the pedals.
For more information see the chapter “The Pedal Systems” as well as the
instructions of the component manufacturers.
6. If you have bought a STEVENS bicycle with suspension, you should ask your
STEVENS dealer to properly adjust the chassis. Improperly adjusted suspen-
sion components are liable to malfunction or damage. In any case, the riding
behaviour deteriorates and you do not achieve maximum riding safety and
riding pleasure.
For more information see the chapters “Suspension Forks” and “Full Sus-
pension of the Mountain Bike Models” further below as well as the instruc-
tions of the component manufacturers.
Danger:
In case you had a crash with your STEVENS bicycle, perform at least the
check described in the chapter “Before Every Ride”. Ride back very care-
fully by taking the shortest route possible, even if your STEVENS bicycle
went through this check without any problems. Do not accelerate or brake
hard and do not ride your bicycle out of the saddle. If you are in doubt,
have yourself picked up by car, instead of taking any risk. Back home you
need to check once again your STEVENS bicycle thoroughly. If you are in
doubt or if you have any questions, contact your STEVENS dealer!
Note:
It is recommendable that you take out a private liability insurance. Contact
your insurance agency. Becoming member in a bicycle association may
also provide insurance coverage.
Danger:
A lack of practice when
using clipless pedals or
too much spring tension
in the mechanism can
lead to a very firm
connection, from which
you cannot quickly step
out. Risk of accident!
Caution:
Prior to towing a trailer
with your STEVENS
bicycle or to mounting
a child seat, read the
chapters “Use of Child
Seats” and “Use of
Trailers” and have a
look at the bike card.
If you are in doubt or if
you have any questions,
ask your STEVENS
dealer.

Before Every Ride
Your STEVENS bicycle has undergone numerous tests during production and
a final check has been carried out by your STEVENS dealer. Nevertheless, be sure
to check the following points before you set off for the first time to exclude any
malfunctioning that may be due to the transport of your STEVENS bicycle or to
changes a third person may have performed on your STEVENS bicycle during a
standstill:
1. Are the quick-release levers or the bolted connections of the front and rear
wheel, the seat post and other components properly closed and tightened?
For more information see the chapter “How to Use Quick-Releases and
Thru Axles” further below as well as the instructions of the component man-
ufacturers.
2. Are the tyres in good condition and do they have sufficient pressure? The
minimum and maximum pressure (in bar or PSI) is indicated on the tyre side.
For more information see the chapter “The Wheels” further below as well as
the instructions of the component manufacturers.
3. Let both wheels rotate freely to check whether the rims run true. Watch the gap
between rim and brake pad or, in the case of disc brakes, between frame and
rim or tyre. Poor concentricity can also be an indication of laterally burst tyres,
broken axles or torn spokes.
For more information see the chapter “The Wheels” further below as well as
the instructions of the component manufacturers.
4. Test the brakes while stationary by firmly pulling the brake levers towards the
handlebar. The brake pads of rim brakes must hit the rim evenly with their
entire surface without touching the tyre during braking, in open condition or
in between. Make sure that you cannot pull the brake levers all the way to the
handlebar and check the hydraulic brake hoses for leaks! Check the thickness
of the brake pads as well.
With disc brakes you should directly get a positive braking response. If you
have to actuate the brake lever more than once to get a positive braking
response, have your STEVENS bicycle checked by your STEVENS dealer.
For more information see the chapter “The Brake System” further below as
well as the instructions of the component manufacturers.
5. Let your STEVENS bicycle bounce on the ground from a small height. If there
is any rattling, see where it comes from. Check the bearings and bolts, if nec-
essary.
6. If you want to ride on public roads, make sure your STEVENS bicycle is
equipped according to the regulations of the respective country. In any case,
riding without lights and reflectors in dark or dim conditions is very dangerous.
A lighting set that corresponds to the regulations is a must on public roads.
Turn on the lights as soon as dusk sets in.
For more information see the chapter “Legal Requirements for Riding on
Public Roads”.
7. In case you have a STEVENS bicycle with suspension, press down on STEVENS
bicycle and see whether the spring elements retract and extend as usual.
For more information see the chapters “Suspension Forks” and “Full Sus-
pension of the Mountain Bike Models” further below as well as the instruc-
tions of the component manufacturers.
8. Make sure that the kickstand, is fully raised before you set off. Risk of accident!
9. Do not forget to take a high quality folding, D- or chain lock with you on your
ride. The only way to effectively protect your STEVENS bicycle against theft is
to lock it to an immovable object.
Danger:
Be aware that the
distance you need to
stop increases, when
you are riding with your
hands on bar ends. The
brake levers are not in
all grip positions within
easy reach.
Danger:
Do not use your
STEVENS bicycle, if
it fails on one these
points! Riding a defec-
tive STEVENS bicycle
can result in serious
accidents! If you are in
doubt or if you have any
questions, contact your
STEVENS dealer.
Danger:
During use your STEVENS bicycle is undergoing stress resulting from the
surface of the road and from the rider’s action. Due to these dynamic
loads, the different parts of your bicycle react with wear and fatigue. Check
your STEVENS bicycle regularly for wear marks, scratches, deformations,
colour changes and any indication of cracking. Components which have
reached the end of their service life may break without previous warning.
Let your STEVENS dealer maintain and service your STEVENS bicycle regu-
larly and in cases of doubt it is always best to replace components.
Danger:
Improperly closed
fastenings can cause
components of your
STEVENS bicycle to
come loose and result in
serious accidents!

Legal Requirements for Riding on Public Roads
If you want to use your STEVENS bicycle for riding on public roads, it has to be
equipped according to the regulations of the respective country.
Pay particular attention to your STEVENS bicycle being equipped with the
required set of lights and reflectors.
Ask your STEVENS dealer to inform you about the regulations in force in the
country where you use your STEVENS bicycle. Make yourself familiar with the road
traffic rules for riding on public roads and off-road.
Danger:
For your own safety, be
sure to switch on the
light as soon as dusk
sets in.
Danger:
Keep the lighting set
clean and check its
functioning at regular
intervals.
Note:
You find more important
tips on cycling in the
chapter “General Safety
Instructions”.
Note:
If you want to use your STEVENS bicycle for riding on public roads, it has
to be equipped according to the regulations of the respective country. Ask
your STEVENS dealer about the regulations in force in your country or in
the country where you intend to use the STEVENS bicycle.
Note:
When riding on public roads cyclists must in general observe the same
traffic rules as car drivers. Make yourself familiar with the road traffic rules
of your country.
S - 26 | English English | S - 27
Adjusting the STEVENS Bicycle to the Rider
Your body height and proportions are decisive for the frame size of your
STEVENS bicycle. Make particularly sure there is enough space between your
crotch and the top tube so that you do not hurt yourself, if you have to get off your
bike quickly.
By choosing a specific type of bicycle you roughly determine the posture you
will be riding in. However, some components of your STEVENS bicycle are espe-
cially designed so that you can adjust them to your body proportions up to a
certain degree. This includes the seat post, the handlebar and stem as well as the
brake levers or brake levers/shifters.
As these adjustments require know-how, experience, appropriate tools and
a certain amount of skill, you should restrict yourself to the adjustment of the
seating position. Ask your STEVENS dealer for the correct seating position or if you
want something changed. They will see to your wishes the next time you leave the
STEVENS bicycle at the workshop, e.g. for the first inspection.
After any adjustment/assembly work, be sure to make a short functional check
as described in the chapter “Before Every Ride” and do a test ride on your
STEVENS bicycle in an area free of traffic.
Danger:
If you have a very small frame, there may be the danger of your foot
colliding with the front wheel. Therefore, make sure that your cleats are
properly adjusted.
Danger:
All tasks described in the following require the know-how of a mechanic
and appropriate tools. Make it a rule to tighten the bolted connections
always with greatest attention. Increase the torque values bit by bit and
check the fit of the component in between. Use a torque wrench and do
not exceed the maximum torque values! You find them on the components
themselves and/or in the chapter “Recommended Torque Settings”.
Note:
If sitting on the saddle causes you trouble, e.g. because it numbs your
crotch, this may be due to the saddle. Your STEVENS dealer has a very
wide range of saddles available and can offer advice on position.
Danger:
When replacing the
saddle, make sure the
saddle rail is compatible
with the seat post. If
you are in doubt or if
you have any questions,
contact your STEVENS
dealer.
Note:
The seating position
depends highly on how
you want to use the
STEVENS bicycle. Ask
your STEVENS dealer
or your trainer for help.
The advices given below
are suitable for typical
cross-country/ mara-
thon bikes suitable.
Adjusting the Saddle to the Correct Height
The correct saddle height depends on the length of your legs. When pedalling,
the ball of your foot should be positioned above the centre of the pedal axle. With
your feet in this position you should not be able to stretch your legs completely
straight at the lowest point, otherwise your pedalling will become awkward. Check
the height of your saddle with flat-soled shoes. This is best done with suitable
cycling shoes. Sit on the saddle and put your heel on the pedal at its lowest point.
Your leg should be fully extended and your hips should remain horizontal.
To adjust the saddle height loosen the quick-release lever (see chapter “How
to Use Quick-Releases and Thru Axles”) or the binder bolt of the seat post
clamp at the top of the seat tube. The latter requires suitable tools, e.g. an Allen
key, with which you turn the bolt two to three turns anticlockwise.
Rule of thumb to determine the suitable saddle height:
Inside leg (barefoot) x 0.885
Now you can perform the vertical adjustment of the seat post. Be sure not to
pull out the seat post too far – the mark on the seat post (max., min., stop or the
like) should always remain within the seat tube – and to grease the surface of an
aluminium or titanium seat post that is inserted into a seat tube made of alumin-
ium, titanium or steel. Do not grease carbon seat posts and/or carbon seat tubes
in the clamping area! Use special carbon assembly paste instead.
Align the saddle with the frame by using the saddle nose and the bottom
bracket or top tube as a reference point.
Danger:
When riding steep
downhill courses on
your mountain bike, a
lower saddle height is
often better for some
riding manoeuvres.
This allows a better
control of your STEVENS
bicycle.
Caution:
If the seat post wobbles
in the seat tube or does
not slide easily, ask your
STEVENS dealer for
advice. Do not use brute
force!
Note:
Children and adoles-
cents need to have the
saddle height and the
position of saddle and
handlebars checked
at least every three
months!
S - 28 | English English | S - 29
Clamp the seat post until it is tight by closing the quick-release, as described
in the chapter “How to Use Quick-Releases and Thru Axles” or by turning the
seat post binder bolts clockwise in half turns. You should not need using great
manual forces to achieve a sufficient clamping effect. Otherwise the seat post
does not match the frame.
Always check between the steps that the seat post is sufficiently tight by hold-
ing the saddle at both ends with your hands and by trying to twist it. If it does,
gently retighten the binder bolt by half a turn and check again.
Is the leg extension correct when you check again? Check by moving your foot
and pedal to the lowest point. When the ball of your foot is exactly above the pedal
centre in the ideal pedalling position, your knee should be slightly bent. If it is,
you have adjusted the saddle height correctly. Check whether you can still reach
the ground safely while sitting on the saddle. If you cannot, you should lower the
saddle a little, at least to begin with.
Danger:
Under no circumstances
grease the seat tube of
a carbon frame. If you
mount a carbon seat
post, do not put any
grease on it, even if the
frame is made of metal.
Once greased, carbon
components may never
again ensure reliable
clamping! Use special
carbon assembly paste
instead.
Danger:
Make sure not to
overtighten the binder
bolt of the seat post
clamp. Otherwise you
may damage the seat
post or the frame. Risk
of accident!
Note:
In the case of height-ad-
justable seat posts, such
as those from RockShox
and Kind Shock, the
height can be adjusted
by pressing a button
on the handlebar. For
more information see
the chapter “Height-Ad-
justable Seat Post/
Dropper Post”. Also read
the instructions of the
manufacturer.
Caution:
Tighten carefully by approaching the prescribed maximum torque value
in small steps (0.5 Nm increments) and check in between the proper fit of
the component. You find them on the components themselves and/or in the
chapter “Recommended Torque Settings”. Do not exceed the maximum
torque value indicated by the manufacturer!
Danger:
Never ride your bike with the seat post drawn out beyond the limit, maxi-
mum, or stop mark! The seat post might break or cause severe damage to
the frame. In the case of frames with seat tubes that extend beyond the top
of the frame’s top tube the seat post should be inserted into the seat tube at
least below the bottom of the top tube and below the top of the seat stays! If
seat post and frame require different minimum insertion depths, you should
opt for the deeper insertion depth.
Adjusting the Height of the Handlebars
The height of the handlebar compared to the saddle and the distance between
saddle and handlebar determine how much your upper body will be inclined for-
ward. Lowering the handlebar gives you a streamlined position and brings more
weight to bear on the front wheel. However, it also entails an extremely forward
leaning posture which is tiring and less comfortable, because it increases the
strain on your wrists, arms, back, upper body and neck.
There are three different stem systems that allow vertical adjustment of the
handlebar, i.e. the conventional, the adjustable and the Aheadset®-stem.
These systems require special knowledge. In this regard, the descriptions here-
after may be incomplete. If you are in doubt or if you have any questions, contact
your STEVENS dealer.
Conventional Stems
Handlebars with conventional stems allow limited vertical adjustment. This is
done by moving the stem up or down inside the fork steerer tube.
For more information see the chapter “Adjusting the Height of the Handle-
bars” as well as the instructions of the component manufacturers.
Danger:
Never ride a STEVENS bicycle with a stem that has been drawn out beyond
the mark for the maximum permissible height! Check all bolted connec-
tions and test your brakes before you set off!
Danger:
The bolted connections of stem and handlebar have to be tightened to
the prescribed torque values. If you disregard the prescribed values, the
handlebar or stem may come loose or break. Use a torque wrench and do
not exceed the maximum torque values! You find them on the components
themselves and/or in the chapter “Recommended Torque Settings”.
Caution:
Never try to unscrew the
top race of the headset
when you only want to
adjust the stem, as you
will otherwise alter the
bearing play!
Danger:
The stem is one of the
load bearing parts of
your STEVENS bicycle.
Changes to it can impair
your safety. If you are in
doubt or if you have any
questions, contact your
STEVENS dealer!
S - 30 | English English | S - 31
Caution:
Keep in mind that
readjusting the position
of the stem changes
the position of the
handlebar, brake levers
and shifters. Readjust
these components,
as described in the
chapter “Adjusting the
Tilt of the Handlebars,
Bar Ends and Brake
Levers”.
Note:
When doing any
adjusting observe the
instructions of the stem
manufacturer. Ask
your STEVENS dealer
to explain to you both
function and adjustment
of your stem or let him
do that work.
Danger:
Do not mount any stem extenders, speed-lifters or the like.
Danger:
Spacers must be removed by the STEVENS dealer only, as this requires the
shortening of the fork steerer.
Danger:
These routines require a certain amount of manual skill and (special) tools
and are best left to your STEVENS dealer. Nevertheless, if you want to try
it by yourself, read the chapter “Adjusting the Height of the Handlebars”
beforehand as well as the instructions of the component manufacturers.
Adjustable Stems
There are various solutions for adjusting the tilt of the front part of adjustable
stems: Some designs use bolts on the sides of the joint, others have bolts on the
upper or bottom side, and other again are equipped with additional locking mech-
anisms or adjusting bolts.
For more information see the chapter “Adjusting the Height of the Handle-
bars” as well as the instructions of the component manufacturers.
Stems for Threadless Systems, the Aheadset®-System
In the case of STEVENS bicycles with Aheadset®the stem also serves to adjust
the bearing preload. If you change the position of the stem you have to readjust
the bearing play.
You can adjust the height to a limited extent by displacing the spacers or by
turning the stem around in the case of flip-flop models, see the chapter “The
Headset”.
Correcting the Fore-to-Aft Position and Tilt of the Saddle
The distance between the handlebar grips and the saddle affects the inclina-
tion of your upper body, and hence your riding comfort and riding dynamics. This
distance can be altered slightly by changing the position of the saddle rails in the
seat post clamp. However, this also influences your pedalling. The rider pedals
more or less from the back. If the saddle is not in horizontal position, the rider
cannot pedal in a relaxed manner. If it is tilted, you will constantly have to lean
against the handlebar to prevent yourself from slipping off the saddle.
Adjusting Saddle Position and Tilt
There are some seat posts mounted STEVENS bicycles which have two Allen
bolts positioned one after the other holding the seat post head and fix the tilt as
well as the horizontal position of the saddle. Some seat posts have two bolts
side-by-side.
Release the bolt(s) at the top of the seat post. Loosen the bolt(s) two to three
turns at the most, otherwise the whole mechanism can fall apart. Move the saddle
forth or back, as desired. You may have to give the saddle a light tap to move it.
With patent seat posts a single bolt fixes the clamping mechanism, which
controls both the tilt and the horizontal position of the saddle. Some seat posts
have two bolts side-by-side.
Observe the marking on the saddle rail and do not go beyond. Make sure
that the top edge of the saddle remains horizontal as you retighten the bolt(s).
STEVENS bicycle should stand on level ground while you adjust the saddle.
Danger:
Poorly tightened or
loosening bolts can fail.
Risk of accident!
Danger:
The adjustment range of
the saddle is very small.
Replacing the stem
allows you to make far
bigger adjustments to
the rider’s fore-to-aft
position, as stems come
in different lengths.
Sometimes, you can
realise a difference of
more than 10cm. In
most cases, the length
of the Bowden and
brake cables must be
adjusted in length, a
job best left to your
STEVENS dealer!
Danger:
Check the bolts by using a torque wrench once a month according to the
values indicated on the components themselves and/or in the instructions
of the component manufacturers.
S - 32 | English English | S - 33
Danger:
Make sure that you
cannot pull the brake
levers all the way to
the handlebar. Your
maximum brake force
should be reached short
of this point.
Note:
If you have hydraulic
brakes and disc brakes,
follow the instructions of
the brake manufacturer.
If you are in doubt or if
you have any questions,
contact your STEVENS
dealer.
Having found your preferred position, make sure that both clamp halves fit
snugly around the saddle rails before tightening the bolt(s) to the correct torque
value as prescribed by the seat post manufacturer.
Retighten the bolt(s) with a torque wrench according to the instructions of the
manufacturer. After fastening the saddle, check whether it resists tilting by bringing
your weight to bear on it once with your hands at either end of the saddle.
Danger:
The bolted connections of the seat post have to be tightened to the
prescribed torque value. Use a torque wrench and do not exceed the max-
imum torque values! You find them on the components themselves and/or
in the chapter “Recommended Torque Settings”.
Danger:
Make sure that the saddle is clamped within the range of the marking on
the saddle rail. Otherwise the saddle rail can fail! Check the bolts by using
a torque wrench once a month according to the values indicated on the
components themselves and/or in the chapter “Recommended Torque
Settings”.
Danger:
The saddle clamping
bolts belong to the most
delicate bolts of the
entire STEVENS bicycle.
Therefore, strictly ob-
serve the recommended
minimum and maximum
torque values. Do not
under- or overtighten.
You find them on the
components themselves
and/or in the chapter
“Recommended Torque
Settings”. Always use a
torque wrench.
Adjusting the Brake Lever Reach
With most brake systems the distance between the brake levers and the han-
dlebar grips is adjustable. This gives in particular riders with small hands the
convenience of bringing the brake levers closer to the handlebars.
On most bicycles there is a small adjusting screw near the point where the
brake cable of a cable brake enters the brake lever unit or at the lever itself. Turn
the bolt clockwise and watch how the lever adjusts as you do so.
With hydraulic brakes you also have adjusting devices at the brake lever. There
are different systems, ask your STEVENS dealer for help or read the instructions
of the component manufacturers. When adjusting the lever reach, make sure the
first phalanx of the index finger reaches around the brake lever. Check the proper
adjustment and functioning of the brake system subsequently, as described in the
chapter “The Brake System” further below as well as in the instructions of the
brake manufacturer.
Adjusting the Tilt of Handlebars, Bar Ends and Brake Levers of
STEVENS Mountain Bikes, Kids’ and Junior Bikes
The handlebars are usually slightly bent at the ends. Set the handlebars to a
position in which your wrists are relaxed and not turned too much outwards.
To adjust the angle of the handlebars, release the Allen bolt(s) on the underside
or front side of the stem. Turn the handlebar to the desired position. Make sure
that the handlebar is accurately centred in the stem. Carefully retighten the bolt(s)
with the torque wrench.
Make sure that the upper and lower clamping slots of the stem are parallel
and identical in width. If you have a stem with several bolts, tighten them evenly in
a cross pattern by using a torque wrench and observe the recommended torque
values.
S - 34 | English English | S - 35
Try rotating the handlebar once clamped in the stem and tighten the bolt a
little more, if necessary. Use a torque wrench and do not exceed the maximum
torque values! You find them on the components themselves and/or in the chapter
“Recommended Torque Settings”.
After adjusting the handlebars you need to adjust the brake levers and shifters.
Release the Allen bolt at either mount. Turn the levers relative to the handlebars.
Sit in the saddle and place your fingers on the brake levers.
Check whether the back of your hand forms a straight line with the line of your
forearm. Retighten the mounts with a torque wrench and do a twist test!
Bar ends and multi position handlebars give you additional ways of gripping
the handlebars. Bar ends are usually fixed in a position that gives the rider a com-
fortable grip when pedalling out of the saddle, i.e. almost parallel to the ground or
tilted slightly upwards (by about 25°).
Release the bolts, which are usually located on the underside of the bar ends,
by one to two complete turns. Turn the bar ends to the desired position making
sure the angle is the same on both sides. Retighten the bolts to the required torque
value. Check whether the bar ends are firmly fixed by trying to twist them out of
position.
Danger:
Be aware that the dis-
tance you need to stop
your bicycle increases,
when you are riding
with your hands on bar
ends or on multi position
handlebars. The brake
levers are not in all grip
positions within easy
reach.
Danger:
Never fix bar ends in
vertical position or with
their ends pointing
rearwards as this would
increase the risk of
injury in the event of an
accident.
Danger:
Make sure that the
fastening bolts of the
cleats are properly
tightened. If they are
loose, disengaging your
shoe from the pedal is
nearly impossible. Risk
of accident!
Note:
Read the operating
instructions of the pedal
and shoe manufactur-
ers carefully. In case
of inquiries, ask your
STEVENS dealer for
advice.
Danger:
Tighten the bolts at the stem until the clamping slots between the stem
body and the faceplate are parallel and identical in width in the top and in
the bottom. Tighten the bolts evenly and in a cross pattern, i.e. alternately
and gradually, by using a torque wrench to the lower value of the recom-
mended torque settings.
The Pedal Systems
Not all shoes are suited for cycling. Shoes used for cycling should have a stiff
sole and provide a firm support for your feet. If the soles are too soft, the pedals
can press through and cause foot pain. The force transmission is less efficient.The
sole should be not too broad near the heels, as the rear stays will otherwise get
in the way of your pedalling. This will prevent your feet from assuming a natural
position and may cause knee pain in the long run.
Different Systems at a Glance – How They Work
We recommend pedals that provide a lock and release mechanism for your
shoe, known as step-in pedals. The firm connection between shoe and pedal pre-
vents your feet from slipping off when pedalling fast or when riding over rough
ground. Besides this, it enables you not only to push but also to pull the pedals,
which makes your pedalling more fluent. A further advantage is that the ball of
your big toe comes to rest biomechanically just at the right place on the pedal axle
and that you do not block unintentionally the front wheel with the tips of your feet
during steering.
With step-in pedals a special cycling shoe forms a lock-in connection with the
pedal, similar to a ski binding.
Danger:
Taking up the pedals, engaging the shoes and disengaging them by turning
the heel outward should first be practised while stationary. Later you can
refine your technique in a place clear of traffic.
Danger:
Only use clipless pedals allowing you to engage and disengage smoothly.
A defective pedal or a badly worn cleat can make the shoe disengage from
the pedal. Risk of accident!
Caution:
Some mountain bike pedals, also referred to as platform pedals, are
designed for maximum grip of the shoes, e.g. for dirtbiking and freeriding.
For this reason they have sharp edges and/or bolted pins. As they enhance
the risk of injuries during riding, you should wear protective clothing, e.g.
knee and shin guards.

To engage with the pedal is to turn it to the horizontal using the tip of the cleat
(the plate on the sole of the shoe) and then rest your foot on it. Most step-in pedals
are equipped with a double-sided lock-in mechanism, so that you can step on the
pedal with either face up. The shoe engages with the pedal with a click which
you will hear and feel clearly. With all commercially available systems the shoe is
disengaged from the pedal by twisting the heel outward.
Lean against a wall or ask someone to hold you when you try to engage and
disengage the shoe from the pedal.
Functional differences between the pedal systems concern the shape of the
cleat, the release angle and the rigidity of the connection. Cyclists predisposed
to knee trouble should choose a pedal system that has some “float”, so that the
heel can move sideways a little while the shoe is engaged with the pedal. Some
step-in pedals have cleats embedded into the sole which is a great advantage, as
it ensures stable walking.
Adjustment and Maintenance
The various pedal systems differ sometimes significantly in their technical
design. Nevertheless, there are some general rules for adjustment which apply
to all of them.
• The cleat has to be fastened to the shoe in such a position that the ball of the
foot comes to rest on the pedal axle.
• Your feet should assume a natural position when pedalling. For most people
this means that the heels will point inward a little. Make sure that the fastening
bolts are properly tightened, as you will find it almost impossible to disengage
your shoe from a loose plate!
• Adjust the release force according to your needs. It is advisable to start with an
inferior preload. Turn the small Allen bolt and check the preload by engaging
and disengaging the shoe from the pedal.
• Exposed springs and other components that attract dirt have to be cleaned and
regreased regularly.
• Squeaking or creaking cleats can often be silenced by applying a little grease
to the point of contact between cleat and pedal. These noises may also be
signs of wear.
• Check the cleats regularly for wear, especially in case of plastic cleats.
• If your shoe wobbles on the pedal, the cleat or the sole of your shoes might
be worn.
Note:
Before mounting the
pedals, check the
marking on the pedal
axles first. “R” stands
for right pedal and “L”
for left pedal. Note that
the left pedal has a
left-handed thread that
has to be tightened
contrary to the direction
you are accustomed to,
i.e. anticlockwise.
The Brake System
Brakes are used for adjusting one’s speed to the surrounding terrain and traf-
fic. In an emergency situation, the brakes must bring the STEVENS bicycle to a
halt as quickly as possible. In the event of such emergency braking, the rider’s
weight shifts forward abruptly, thus reducing the load on the rear wheel. On a
grippy surface it is therefore more likely that the rear wheel will come up and
that the STEVENS bicycle will overturn than that the tyres will lose grip. Such a
problem becomes particularly acute when riding downhill. Therefore, in case of an
emergency braking situation you must try to shift your weight back and down as
far as possible.
Actuate both brakes simultaneously and bear in mind that due to the weight
shift the front brakes can achieve a higher braking force.
With rim brakes long lasting braking or permanent dragging of the brake
pads can overheat the rim. This can affect the inner tube negatively or cause the
tyre to slip on the inner rim. Sudden loss of pressure while cycling can result in a
serious accident.
With disc brakes prolonged braking or permanent dragging of brake pads can
overheat the brake system. This can result in a loss of braking force, even to the
point of total brake failure, provoking serious accidents.
Therefore, check your riding manners and make it a habit to brake hard and
then to open the brake again, whenever the road surface and the situation allows
it. It is better to stop for a moment and let the rim cool down with the brake lever
released rather than to risk anything.
Functioning and Wear
Actuating the hand lever on the handlebar causes a stationary brake pad to
be pressed against a rotating braking surface generating friction. The resulting
friction slows down the wheel. The rate of deceleration is not only determined by
the force with which the brake pad is pressed against the braking surface, but
also to a decisive degree by the coefficient of friction, which depends on the two
materials that are rubbed against each other.
When water, dirt or oil gets in contact with one of the engaging surfaces, this
changes the coefficient of friction. This is why brakes respond at a slight delay and
less powerfully in wet weather. This applies in particular to rim brakes.
In order to maintain their effectiveness brakes need to be checked and read-
justed from time to time.
Danger:
Be careful while getting
used to the brakes.
Practise emergency
stops in a place clear
of traffic until you are
comfortable controlling
your STEVENS bicycle.
This can save you from
having accidents.
Danger:
Ensure that braking
surfaces and brake
pads are absolutely free
of wax, grease and oil.
Risk of accident!

Rim Brakes (General)
The friction generated by braking causes wear to the brake pads as well as
to the rims. Frequent rides in the rain and soiling hasten wear on both engaging
surfaces. Once the abrasion of the rim has reached a certain critical point, the rim
may break under the tyre pressure. This can make the wheel jam or the inner tube
burst, both of which can cause a fall!
Contact your STEVENS dealer and have the remaining thickness of the rims
checked when you have worn through your second set of brake pads at the latest.
The rim thickness can be checked by a specialist with special measuring instru-
ments.
Some rims are provided with wear indicators. Once the abrasion of the rim
has reached a certain critical point, the brake indicator becomes visible in form
of small slots or a permanent strip or disappears (according to the model). In this
case you should also contact your STEVENS dealer at once and have your rim
replaced.
Checking, Readjusting and Synchronizing V-Brakes
Common V-brake designs have two brake arms mounted separately on either
side of the rim. Actuating the brake lever creates a pull on the brake cable which
draws the arms towards each other. On this occasion the brake arms turn slightly
inwards around the suspension point, a friction of the brake pads being generated
on the rim sides.
Caution:
When replacing any
parts, be sure to only
use parts that bear the
appropriate mark and,
to be on the safe side,
original spare parts. Your
STEVENS dealer will be
pleased to help you.
Danger:
Damaged brake cables
that are for example
frayed should be
replaced immediately,
as they can otherwise
fail in a critical moment,
possibly causing a
crash.
Danger:
Clean the brake pads at
regular intervals.
Danger:
Wet weather reduces the braking effect and the road grip of the tyres. Be
aware of longer stopping distances when riding in the rain, reduce your
speed and actuate the brakes carefully.
Danger:
The assignment of brake lever to brake calliper can vary, e.g. left lever acts
on front brake. Have a look at the bike card and check whether the brake
lever of the front brake is on the side you are used to (right or left). If it is
not, ask your STEVENS dealer to switch the brake levers before you set off
for the first time.
Danger:
When replacing brake pads, be sure to only use marked brake pads
matching your rim. Your STEVENS dealer will be pleased to help you.
Ensure that braking surfaces are absolutely free of wax, grease and oil.
Ask an expert to check the rims at the latest when you are through your
second set of brake pads or when the wear indicators are visible. Worn
down rims may make the inner tube burst and result in a fall! Ask your
STEVENS dealer for help.
Functional Check
• Check whether the brake pads are accurately aligned with the rims and still
sufficiently thick. You can tell this by the grooves in the brake pads. If the pads
are worn down, it is time to replace them.
• Furthermore, the brake pads should touch the rim with their front part first.
At the moment of the first contact the rear part of the brake pad should be a
millimetre away from the rim. Seen from the top the brake pads form a “V”
with the trough pointing to the front. This V-shaped setting prevents screeching
when the brakes are applied.
• When you pull the brake lever, both brake arms must contact the rim simul-
taneously.
• The brake lever must always remain clear of the handlebars. You should not be
able to pull it all the way to the handlebars, even in the event of an emergency
braking.
• Only a successful passing of all these points will ensure a correctly adjusted
brake.
Vertical Adjustment of the Brake Pads
• Release the fastening bolt of the brake pad by one to at most two complete
turns.
• Push the brake pad to the correct height, i.e. the brake pad must hit the rim
with its entire surface. Make sure the brake pad is in parallel to the rim and pull
the brake lever to fix the brake pads. Retighten the fastening bolt of the brake
pad to the recommended torque value.
