WARNINGS AND IMPORTANT INFORMATION
2
WARNING: This bicycle is not meant
for public road use. It is meant for off
road use only. This bicycle is designed
for riding on rougher surfaces. You may
use it for man-made dirt jumps, skate
parks, ramps, as well as other plac-
es where you will need skill and bike
control. Please note that by this type of
riding unpredictable forces are put on a
bicycle which may overload the frame,
fork, or parts. The fact that you use a
dirt jumping bike does not mean you
have skills to jump.
WARNING: If you intend to use the bike
on public roads, you must prepare the
bicycle to meet the local requirements
for items such as lights and reectors.
Always follow all local trafc laws and
regulations in force on public roads as
well as off-road, including regulations
about bicycle lighting, reectors, licens-
ing of bicycles, riding on pavements,
laws regulating bike path and trail use,
helmet laws, child carrier laws and oth-
er special bicycle trafc laws.
WARNING: Extreme riding is a very
dangerous sport; it requires an amazing
amount of skill. By engaging in this type
of activity, you are accepting the risk of
possible injury or even death. Even the
best bike will not help you land a clean
trick. Even the best protective gear will
not guarantee complete safety. Remem-
ber that in this kind of riding, you can
only trust your own abilities and you
must accept the inherent risk.
While extreme riding you can reach
signicant speeds and therefore face
similar hazards and risks. Inspect your
bicycle and equipment carefully and
be sure that it is in perfect condition. If
possible consult with area site person-
nel, expert riders and race ofcials on
conditions and equipment advisable.
Always wear appropriate safety gear,
including an approved (full face) helmet,
full nger gloves, body armour, bright,
visible clothing that is not so loose
that it can be tangled in the bicycle or
objects at the side of the road or trail,
shoes that will stay on your feet and will
grip the pedals (make sure that shoe
laces cannot get into moving parts, and
never ride barefoot or in sandals). Al-
ways use protective eyewear, to protect
against dirt, dust and bugs.
WARNING: Some of the service proce-
dures require specialist tools and good
mechanical skills. Therefore, to mini-
mise the risk of serious or even fatal
accidents, we reccomend that mainte-
nance and assembly work on your bike
is carried out by an authorised bicycle
workshop.
IMPORTANT NOTICE: This manual is
not intended as a comprehensive use,
service, repair or maintenance manual.
Please consult your dealer for advice
and your dealer may also be able to
refer you to classes, clinics or books on
bicycle use, service, repair or mainte-
nance.
WARNING: The bike box contains
instructions for components made by
third parties. You must study these
carefully and follow the directions be-
fore riding your bike.
INFORMATION: The maximum total
weight allowed (rider + clothing + pro-
tective gear + backpack, luggage etc.)
is 120 kg.
WARNING: Never carry anything which
obstructs your vision or your complete
control of the bicycle, or which could
become entangled in the moving parts
of the bicycle.
WARNING: The stem & handlebar
must be connected rmly with the fork.
Otherwise the whole steering system
may fail and cause you to lose control
of the bicycle. This may result in injury
and death.
WARNING: Do not extend the seat post
above the minimum insertion mark.
WARNING: Alloy handlebars should be
replaced at least once a year because
they can snap suddenly with no warning
if submitted to fatigue stress for a pro-
longed period of time.
WARNING: As with all mechanical
components, the bicycle is subjected to
wear and high stresses. Different mate-
rials and components may react to wear
or stress fatigue in different ways. If the
design life of a component has been
exceeded, it may suddenly fail possibly
causing injuries to rider. Any form of
crack, scratches or change of colour in
highly stressed areas indicate that the
life of the component has been reached
and it should be replaced. When re-
placing any components, especially the
safety-critical ones, genuine spare parts
complying with your bike specications
are to be used only.
NOTE FOR PARENTS AND GUARDI-
ANS: As a parent or guardian, you are
responsible for the safety of the child
under your supervision. This, amongst
other things, includes making sure that
the bicycle is properly tted, adjusted,
and that it is in good condition. Be sure
that you and the child have learned and
understand how to operate the bicycle
safely in the enviroment that you plan
to ride.
The manual provided by the part man-
ufacturer contains full comprehensive
details.
WARNING: Make sure that your child
always wears an approved bicycle
helmet when riding. At the same time,
make sure that your child understands
that a bicycle helmet is to be used
only on the bike, and must be removed
when not riding. A helmet should never
be worn while playing, on playground
equipment, while climbing trees, or at
any time while not riding a bicycle. Fail-
ure to follow this warning could result in
serious injury or death.

ASSEMBLING YOUR SECT BIKE
4
Your Sect complete arrives partially as-
sembled. Just a few short steps need
to be taken before you are out riding it!
STEP 1. Bar and Stem assembly
First of all you need to straighten your
bars out of the box. Do this by lining
them up with you front wheel and tight-
ening your stems steerer clamp.
Warning: Make sure your headset is
tight after this procedure. Also make
sure your stem is facing the correct
way (as shown in image below)
To tighten the headset you need to
make sure the stem is loose on your
steerer (the two bolts towards the back
of the stem). Once these are undone
you can tighten you headset preload on
the top cap of your stem. Once your
headset has no forwards/backwards
movement and remains easy to turn
left to right you are ready to tighten the
stem/steerer bolts towards the back of
the stem. Make sure you tighten these
to the reccomended torque. See Table 1
Bar clamps should be fastened seper-
ately. Torque gures can be found on
the previous page or see Table 1.
STEP 2. Pedal tting
The pedals will be included in the box
and ready to install. Make sure you use
grease on the axles and that the pedals
are on the correct side. There should
be an indicator on the axle to distin-
guish betweek left and right.
Tighten each pedal up using the allen
head on the inside of the axle.
IMPORTANT
Please Note: The left hand pedal axle
is reverse threaded. To tighten please
turn the opposite way to normal.
STEP 3. Final check
Before riding you need to check through
your bike making sure each part is
tightened to the correct torque setting
and your tyres are at a suitable pres-
sure. Check the Torque list below for
reference alongside the image on the
previous page.
1• Steerer clamp - 14 Nm
2• Bar Clamp bolts - 6Nm
3• Brake Mounting bolts - 6Nm
4• Seat Clamp bolt - 10Nm
5• Wheel nuts - 30Nm
6• Pedals - 30-34Nm
7• Crank pinch bolts - 12-14Nm
Tyres should be inflated between 30psi
and 60psi. The valve type for this bike
is schrader (car type).
Final check will include chain tension
adjustment. The DMR sect is a single-
speed MTB so the chain is tightened
by moving the wheel further back in the
frame.
Note: When doing this make sure that
the wheel is straight with the rest of the
bike
Move wheel backwards to ensure the
chain is tight. See general riding info 3
Brake can be aligned using the allen
bolts located on the TOP of the brake
caliper. Check your brake before rid-
ing and make sure your pads are bed
in before braking sharply.
GENERAL RIDING INFORMATION 1
5
As mentioned, riding a bike, in particu-
lar an off-road one, can be dangerous.
You must keep this in mind and be
cautious at all times. See and be seen.
Use lights and reective clothing in low
light conditions at all times. If the bike is
to be used by your child, make certain
that it always wears a suitable and
approved bicycle helmet when using
the bike. If your bike has suspension,
please be noted that it can alter the way
the bicycle performs.
Riding with a wheel that has not been
properly secured can make the wheel
wobble or disengage from the bicycle
resulting in serious injury or death.
WARNING: Reectors are not to be
used as a substitute for required lights.
You should abide by the local bicycle
lighting regulations. Riding at times
of poor visibility such as dawn, dusk,
night or others, without a proper bicycle
lighting system and reectors consti-
tutes a hazard and may cause serious
injury or death. You should examine
the bike lights and reectors along with
their mounting brackets regularly to
make sure that they are clean, straight,
unbroken and properly and securely
mounted.
WARNING: When your bike is on a
bike stand or it’s upside down, never
put your nger or any other part of your
body between the chain and the chain-
ring when the wheel is spinning. This
is especially important on single speed
bikes with no derailleurs, because the
chain is very tight. It is very easy to
have your nger crushed or even ampu-
tated in such a situation!
Always conduct a pre-ride check
(detailed information can be found
further in this manual). Never ride the
bicycle if you observe any technical
problems or have any doubts about
the proper functioning of any element
in the bicycle. Keep the bike clean
and well maintained. Make sure that
your parts of the body as well as any
other objects do not touch the sharp
teeth of the chainrings, chainwheels,
sprockets, chain, cranks, or spinning
wheels of your bicycle. While using an
off-road bike you are to comply with the
following rules: you need to pay close
attention and use the specic skills
required in the changeable conditions
and dangers associated with off-road
riding. You should start slowly in un-
complicated terrain and develop your
skills gradually. You shouldn’t ride your
bike in remote areas unaccompanied.
Even when riding in the company of
others, always let someone know where
you’re going and when you expect to
come back. Always keep some sort of
identication with you, so that you could
be identied in case of an accident;
also you should always have some
cash for food, a cold beverage or an
emergency phone call on you. It may be
difcult to nd help when you’re riding
off-road. You should abide by the local
regulations determining the places and
methods of off-road riding, and respect
private property. Respect the rights of
the others you may be sharing the trail
with — hikers, equestrians or other
cyclists. You should reduce your impact
on the environment to minimum. Thus,
never cut your own trails or shortcuts
through vegetation or streams, which
could disturb the ecosystem. Don’t ride
in mud or sludge or with unnecessary
sliding as such behaviour could con-
tribute to erosion. Always leave things
as how you nd them and take out
everything that you bring in with you.
In case of an accident or impact: rst
take care of your own situation – check
yourself for injuries, and take the best
possible care of them. Get medical help
if necessary. Then, check your bike
for damage. After a crash of any kind,
you should have your bike thoroughly
checked by your dealer. You must not
use the carbon composite components,
such as frames, wheels, handlebars,
stems, cranksets, forks, brakes, etc.
which have sustained an impact until
they have been disassembled and
thoroughly inspected by a qualied
mechanic. The bicycle components
can undergo unusual stress due to a
crash or impact of other kind, causing
their premature fatigue. Components
suffering from stress fatigue can break
suddenly and catastrophically, which
may result in your losing control, seri-
ous injury or death.
Always carry a pump, spare inner tube,
patch kit, and a basic tool kit. You may
need this in case of a at tire or other
common mechanical problem that is
usually easy to x if you have the right
tools. If you need to patch your inner
tubes, always make sure to follow the
instruction manual provided by the tube
repair kit manufacturer. If sold in UK,
Japan, Australia and other left-hand
drive countries, the bikes should come
with right lever operating the front brake
and left lever operating the rear brake.
In countries with right-hand drive trafc
systems, the bikes should come with
right lever operating the rear brake
and the left lever operating the front
brake. The user must check and make
sure which lever is connected to which
brake before the rst ride because it is
possible that the bicycle was imported
from a country where brakes are set
up differently to the standards applying
in the country where the bicycle will be
used. Protect your bike against theft
by purchasing a lock and never leaving
your bike unlocked while unattended,
even if you are going to leave it only for
a short while.
CAUTION: Watch out for the brakes
— they can be powerful and activating
them too aggressively can result in a
crash. Learn to get a feel of the brakes
practicing it on a side road or in an
empty car park before you ride your
bike for the rst time.
WARNING: Wet weather conditions
dramatically increase the risk of an
accident as they impair traction, braking
and visibility, both for the cyclist and for
other road users. Wet conditions dra-
matically reduce the stopping power of
your brakes (especially rim brakes) as
well as of the brakes of other vehicles
sharing the road and your tires can lose
their grip. Therefore, it is more difcult
to control your speed and you may lose
control easily in such conditions. To
make sure that you are able to reduce
speed and come to a stop safely in wet
conditions, try to ride more slowly and
start braking earlier and more gradu-
ally than you would under normal dry
conditions.
Bicycle Suspension
If your bicycle has been equipped with
any sort of a suspension system, make
sure you read and follow the suspen-
sion set up and service instruction
manual provided by the manufacturer. If
you haven’t been provided by the man-
ufacturer’s instruction manual, contact
your dealer or the manufacturer. See
GENERAL RIDING INFORMATION 2
6
instructions attached at end of manual.
WARNING: Failure to maintain, check
and properly adjust the suspension sys-
tem may cause suspension malfunction,
in result of which you may lose control
and fall.
If your bike has been equipped with
suspension, the increased speed you
may develop will also increase the risk
of injury. For example, when braking,
the front of a bike with a suspension
fork dip. You can easily lose control
and fall if you are not prepared for this.
Please, learn how to operate your sus-
pension system safely.
WARNING: Introducing changes in the
suspension adjustment can alter the
handling and braking characteristics of
your bicycle. It is forbidden to change
the suspension adjustment unless you
are thoroughly familiar with the suspen-
sion system manufacturer’s instructions
and recommendations; you should
always check for changes in the han-
dling and braking characteristics of the
bicycle after the suspension has been
adjusted by taking a careful test ride in
a safe area.
Thanks to the use of suspension the
wheels can follow the terrain better,
which can enhance control and comfort.
This improved capacity may provide
opportunity for riding faster, but you
should be careful not to mistake the
enhanced capabilities of the bicycle for
your own riding skills. Improving skills
takes time and practice.
CAUTION: Not every bicycle can be
safely retrotted with certain types of
suspension systems. Before planning
to retrot a bicycle with any suspen-
sion system, check with the bicycle’s
manufacturer to make sure that the
modication you are going to make is
compatible with the bicycle’s design.
Failure to do so can result in damage to
the frame and your bicycle may be dif-
cult to control due to improper geometry
that results from the modication.
IMPORTANT: make sure your wheels
function properly before each use,
check if the mounting bolts are secure,
check that the freewheel engages cor-
rectly. If there is any malfunction of the
hubs, they should not be used under
any condition. In case of any doubt,
consult an experienced bike mechanic.
Rear hub axle bolts should be tightened
alternately! Do not over-tighten the bolt
on one side without counter tightening
on the other!
Brakes
There are two main types of bicy-
cle brakes: rim brakes, operated by
squeezing the wheel rim between two
brake pads and disc brakes, operat-
ed by squeezing a hub-mounted disc
between two brake pads. Both can be
actuated by the rider squeezing a lever
mounted on the handlebar.
WARNING: Riding with brakes that
have not been adjusted properly, worn
brake pads, or wheels with a visible
rim wear marks constitutes a hazard
and can cause serious injury or death.
Too hard or too sudden application of
the brakes can cause the wheel to lock
up and make you lose control and fall.
Applying the front brake too suddenly
or excessively may result in the rider’s
pitching over the handlebars, potentially
causing serious injury or death. Bicycle
brakes may be very powerful, especially
disc brakes or linear-pull brakes. You
should be extra careful while learning
how to operate such brakes and take
particular care while using them. Disc
brakes can heat up extremely when
their application is prolonged. Don’t
touch a disc brake until it has had
plenty of time to cool. Remember that
brake pads in all brake types will wear
out, which will ultimately reduce their
efciency. For information on how to
operate and maintain your brakes and
when to replace the brake pads see
the brake manufacturer’s operation
and maintenance manual. If you have
not been provided with the manufac-
turer’s instruction manual, contact your
dealer or the brake manufacturer. When
replacing worn or damaged parts the
manufacturer-approved genuine spare
parts are to be used only. Brake con-
trols and features
It’s vital for your safety to learn and
remember which brake is controlled by
which brake lever on your bike. Ac-
quaint yourself with the setup of your
brakes by alternately squeezing the
left and right brake lever and observing
which brake lever activates the front
brake, and which one activates the rear
brake. You should be able to reach
the brake levers with your hands and
squeeze them easily. If you nd out that
your hands are too small to do so, you
should consult it with your dealer before
riding the bike. In some models the le-
ver reach may be adjusted, or you may
need a different brake lever design.
Operation of the braking system
The bicycle braking system’s func-
tion is based on friction between two
braking surfaces. To assure its proper
functioning you should maintain the
rims, brake pads, disc rotor and calliper
clean and free of dust, dirt, grease,
lubricants, waxes and polishes. There
are special chemical cleaners available
on the market designed specically for
cleaning these surfaces. Bicycle brakes
have been designed to control the
speed of your bicycle by reducing it or
preventing the bicycle from moving. The
maximum breaking force for each wheel
is achieved just before the moment the
wheel stops rotating (“locks up”) and
starts skidding. The instant it has begun
to skid, the most of your bike’s stopping
power and all directional control is lost.
Therefore, it is necessary to learn how
to slow down your bike and bring it to a
halt smoothly avoiding a wheel lockup.
To do so, you should learn a progres-
sive brake modulation technique so
that you could be able to precisely and
accurately control the amount of clamp
force on a rotor with a given amount
of lever input. Instead of pushing the
brake lever abruptly, squeeze it slow-
ly, and gradually increase the braking
force. The instant the wheel begins to
lock up, slightly release pressure to
keep it rotating. You should learn how
much brake lever pressure is needed
for each wheel at different speeds and
on different surfaces. Reducing the
bike speed by applying one or both
brakes will transfer the weight to the
front wheel as the rider’s body contin-
ues at the speed at which it was going.
Heavy braking will result in the trans-
fer of weight around the front wheel
hub, which may send the rider’s body
ying over the handlebars. Greater
brake pressure is needed for a wheel
burdened with heavier load to lock
up, whereas a wheel burdened with
less weight will lock up with less brake
pressure applied. Thus, when your
weight is transferred forward when the
brakes are activate, you should move
GENERAL RIDING INFORMATION 3
7
your body backwards in order to trans-
fer weight to the back, simultaneously
decreasing the rear braking force and
increasing the front braking force. It is
especially important when you are de-
scending. The weight transfer is more
evident on bikes equipped with a front
suspension fork as it dips under braking
and thus intensies the weight transfer.
To control your speed effectively and
bring your bike to a halt safely you need
to be in control of the wheel lockup and
the weight transfer. You should practice
braking and weight transfer techniques
in safe places free from trafc and
distractions.
CAUTION: It is crucial to apply correct
tightening force on fasteners, nuts,
bolts, screws on your bicycle so as to
avoid components’ failure or damage,
which can result in your losing control
of the bike and falling. Using too little
force may result in the fastener not
holding securely, moving and under-
going fatigue. Applying too much force
may cause the fastener to strip threads,
stretch, deform or break. If you observe
any problems at the pre-ride check,
consult a professional bicycle mechanic
instantly for advice. Before every ride
You should always make a pre-ride
check. It should include the following
points: Clean the frame and fork and
examine them CAREFULLY for any
signs of cracks, corrosion, dents, paint
peeling or other defects. If anything
suspicious is found, contact your local
bike dealer for a proper inspection.
These are important safety checks and
very important to help prevent acci-
dents, injury and shortened product
lifespan. Do not ride the bicycle if you
see any defects in the frame and fork.
Check if the brakes are working proper-
ly by testing their efciency in a parking
lot or on a side road. When the brake
is applied with full force, the distance
from the brake lever to the handlebar
should be bigger than 2 cm. Check the
brake pads too - you should replace
damaged and worn out elements and
adjust immediately when improper func-
tion is noticed. To do this, contact your
dealer or the closest authorised bike
service. Remember that improper setup
of the brake can cause serious injury or
death. Follow the brake manufacturer’s
instructions closely for setup and main-
tenance. The instructions are supplied
in the box with every bicycle. If you are
in doubt about their correct function,
contact your local bicycle shop.
Control position adjustments
It is possible to adjust the angle and
position of brakes and shift controls on
the handlebars. Ask your dealer or bike
shop to make the necessary adjust-
ments for you. If you choose to adjust
the control lever angle on your own, be
sure to re-tighten the clamp fasteners
to the recommended torque (see the
manufacturer’s instruction manual).
Brake reach
In many bikes brake levers can be
adjusted for reach. If your hands are
small or if squeezing the brake levers
is difcult for you, ask your dealer to
adjust the reach or have shorter reach
brake levers tted.
WARNING: With shorter brake lever
reach, correct adjustment of brakes be-
comes more critical, full braking power
should be applied within available brake
lever travel. Brake lever travel inade-
quate for full braking power application
can result in loss of control, which may
cause serious injury or death.
Check the brake cables and their hous-
ing for kinks, rust, broken strands, or
frayed ends. If you notice any damage,
you should ask a bicycle shop to re-
place the cables immediately. Damaged
cables can seriously impede braking ef-
ciency. If your bicycle has rim brakes,
inspect the rim walls to check if they are
not excessively worn out by the brakes.
A groove made by manufacturer on
the sidewall of a rim should always be
visible. On rims without a groove/safety
mark it is important to check if the brak-
ing surface has not become deformed
by the brake pads. The rims should be
replaced as soon as a visible deforma-
tion of the rim surface occurs.
For your information: in some
jurisdictions there are requirements
to determine the minimum leg-length
dimension (clearance between the
rider’s crotch and the top tube of the
bike when stood in front of the saddle)
in the manual. This does not apply to
all bicycles, yet the so called stand
over height constitutes a basic element
of bike t and plays an important role,
especially when dismounting the bike
quickly. While determining the correct
stand over height you should strad-
dle your bike while wearing the kind
of shoes which you are going to wear
while riding, and bounce energetically
on your heels. Your crotch touching
the frame means that the bike is too
big for you. You should not ride the a
bike. The minimum stand over height
clearance for the bike ridden on paved
surfaces only and never taken off-road
should be 5 cm (approx. 2 inches). The
minimum stand over height clearance
for the bike to be ridden on unpaved
surfaces should be 7.5 cm (approx. 3
inches). The minimum stand over height
clearance for the bike to be used off
road should be 10 cm (four inches) or
more. Stand over height does not apply
to bicycles with step-through frames. In
such bicycles the range of the saddle
height determines the limiting dimen-
sion. Make sure you are able to adjust
the position of your saddle as shown
in this manual herein above without
exceeding the limits set by the height of
the top of the seat tube and the mini-
mum insertion or maximum extension
mark on the seat post. Remember that
toe-clearance may vary according to
any modications introduced to tires or
cranks.
Steering system.
The steering system includes: handle
bar, stem, headset and fork. All ele-
ments should be connected rmly for
riding safety.
WARNING: Proper assembly and func-
tioning of the steering system is critical
for your safety!!!
GENERAL PRE-RIDE CHECK
8
• Check the connection between the
handlebars and stem. Try pushing the
handlebars up and down - there should
be no movement between these two
elements. If there is any, it is necessary
to tighten the stem bolts (shown above).
• Check the headset for play (stand
next to the bicycle, apply the front brake
and push forwards and backwards.
There should be no play between the
frame and fork). If any play is found
contact your local bike shop or If you
are a condent mechanic then adjust
this yourself. Follow these steps:
Loosen the steer clamp binder bolts.
Adjust preload until no binding or
looseness are present in the headset.
(Shown above) Align the stem with the
front wheel and now tighten the steer
clamp binder bolts alternately, in small
increments. Once again, check for
headset play. If play exists, loosen the
steer clamp, pinch bolts, and tighten
the top cap anchor bolt 1/16th of a turn.
Align the stem, and retighten the pinch
bolts Remember to tighten both bolts
alternately. Repeat until proper adjust-
ment made. All parts of the stem should
be regularly checked for damage or
cracks. If you nd anything suspicious,
contact an experienced bike mechanic
immediately. A defective steering sys-
tem can cause serious injury or death.
• Check if the wheels are straight (lift
the bike and spin each wheel - the rim
should not move more than around
1 mm to each side). Check if all the
spokes are tight by running your hand
around each wheel on both sides.
Contact your bicycle dealer to resolve
any problems. Do not attempt to ride a
bicycle with wheels that are not straight
or with spokes that are loose, as it is a
danger to your health and life.
• Check if the tyres are properly inated
(see the prints on the side walls for in-
structions about the optimum pressure:
usually 30 – 50 psi depending on terrain
and weather conditions). Use a proper
bicycle pump with a pressure gauge to
achieve the correct pressure.
• Check the overall conditions of the
tyres, if they are damaged, torn or worn
out you should replace them before
riding. Using worn or damaged tyres is
dangerous to your health and life. Make
sure tyres are correctly inated and are
in good shape. Spin each wheel slowly
and look for cuts in the tread and side-
wall. Replace damaged tyres before
riding the bike.
• Proper fork maintenance is essential
for long life and optimal fork function.
Lack of maintenance may result in
faster wear and may lead to malfunction
causing serious injury or death. If you
are not sure how to maintain the fork,
you should consult your dealer to help
you with your maintenance require-
ments.
• Do not ride if any defects are noticed!
• For information about servicing sus-
pension forks mounted on the bike it is
necessary to follow the manufacturer’s
instructions closely. The user manual
for the suspension forks is supplied in
the box with every bicycle and at the
end of this manual.
• Check wheel axle to fork connection
- this is critical for your safety. If you
have axle nuts they should be tightened
according to the wheel manufacturer’s
specication.
GENERAL MAINTENANCE AND PERIODICAL CHECKS
9
Take care of your bicycle, and you will
enjoy it for a longer time. Also take
some time to periodically inspect the
bicycle in more detail - this is important
for your safety. Here is some basic
information.
Caring for steel frames
Steel frames are prone to corrosion if
not taken care of properly. If you have a
steel frame a good rust inhibitor should
be applied to it’s inner surface by
spraying it through the head tube, seat
tube and bottom bracket at least once a
year. Regular cleaning will remove salt
and other chemicals from the surface
of your bicycle minimising the likelihood
of external corrosion. It is very impor-
tant that paint chips and scratches get
touched up as soon as possible with
factory touch-up paint or nail polish.
Prior to painting, make sure that the
surface is free of rust, clean
and dry. The frame does not require
any lubrication with the exception of the
seat clamp bolt area (if it is integrated
with the frame).
Periodical checks
A brief inspection of the frame, fork and
bars for any signs of damage should be
done prior to every ride. If you suspect
it may be broken, bent, cracked, do
not use it. Inspect if the steer tube and
fork blades are straight and dropouts
for cracks or damage. Do not ride on
the damaged fork - it may cause serious
injury or death.
A good time to give your bike a thorough
check for cracks or other defects is when
you are washing it since the problems will
become easier to see. When inspecting
your bicycle make sure the lighting is
good (eg. outdoors). Check the bike on
it’s wheels, and then turn it upside-down
and check it again.
WARNING: The handlebars should be
replaced at least once a year as they are
submitted to fatigue.
Check the cranks for play (hold the bike
with one hand, and the pedals with the
other and look for play by trying to push
the pedals from one side of the bike to
the other). If any play is found, contact
your local bike shop. Periodically check
hubs for play and have the bearings
adjusted if necessary by a professional
bicycle mechanic. The bearings should
be lubricated about once a year. Keep
your chain cleaned and lubed. This is
especially important if you ride often in
wet conditions. Use proper bicycle chain
lubricants.
WARNING: As for all mechanical compo-
nents, the bicycle is subject to wear and
tear as well as high stresses. Nothing
lasts forever! The reaction of various ma-
terials and components to wear or stress
fatigue may differ. Having exceeded the
life expectancy of a component may re-
sult in its sudden failure, possibly causing
injuries to the rider. Any forms of breaks,
cracks, scratches or changes of colouring
in highly stressed areas indicate that the
life of the component has been reached
and it should be replaced.
Cleaning your bicycle
Good maintenance will increase the life
of your bike and its components. Clean
and maintain your bike regularly.
WARNING: Corrosion can damage com-
ponents of your bike which are important
for safety so that they are no longer se-
cure. These components may then brake
during riding and thus result in serious
falls. Corrosion is caused, amongst other
things, by salt (e.g. due to salt spread-
ing in winter), salty air (e.g in coastal or
industrial areas), perspiration.
For wet cleaning, use a gentle water jet
or a bucket of water and a sponge or
brush. Only use clean fresh water or de-
salinated water. There are many ways of
washing a bike. A proven cleaning recom-
mendation for a dirty bike is as follows:
1/ With a gentle water jet, remove large
items of debris such as soil, stones and
sand etc. 2/ Let the bike dry off to a cer-
tain extent. 3/ Spray your entire bike with
a suitable detergent.
4/ Rinse the entire bike with a gentle
water jet and allow it to dry. 5/ Clean the
chain (see below for details).
NOTE: If there is only a low level of soil-
ing, simply spraying on a detergent and
rinsing it off after the specied time for
them to work is sufcient.
NOTE: Stubborn dirt which usually
accumulates in the drivetrain area can be
removed with a stronger degreaser and
brush.
WARNING: Cleaning, lubrication and
preserving agents are chemical products.
Incorrect use can damage your bike. Only
use products expressly suitable for bikes.
Ensure that these products do not attack
either paint, rubber, plastic or metal parts
etc. Consult your dealer and follow the
respective manufacturer‘s instructions.
Cleaning and lubricating the chain
NOTE: Your chain should be cleaned and
lubricated periodically - approximately
once every 10 rides, after every ride in
wet conditions, and every time you wash
your bike.
Drip a suitable chain cleaner into a clean,
spirit-free cotton cloth and wipe the chain
down. When doing so, slowly operate the
crank against the direction of drive. Re-
peat this process a few times with a clean
area of the cloth until the chain is clean.
Sparingly apply
a lubricant suitable for bicycle chains to
each chain link.
NOTE: Only use lubricants expressly ap-
proved for use with bike chains. Greases
for motor cycle chains will gum up your
bike chain and the drive chain compo-
nents.
NOTE: If cleaner remains between the
chain links, the new grease will be imme-
diately broken down and will be totally
ineffective.
