A Word About Bicycles,
Accidents, and Safety
A bicycle can be fun when used for
transportation, recreation, exercise, or
competition. But riding a bicycle can also be
dangerous, especially if you try to ride beyond
the limits of your ability or the limits of your
bicycle. The skill of bicycle riders can vary
greatly, just like the skill of an automobile driver
or a skier. Do not ride in a manner that exceeds
your ability.
Each bicycle also has limits because of many
properties:
• Design and material of the bicycle
• Maintenance and use of the bicycle
• Surface of the road or trail
• And more
An Impact can Weaken your Bicycle
If you crash or apply force that is higher than
the limits of your bicycle, you are very likely to
cause damage to the bicycle or its parts. If your
bicycle has damage and you crash or load it
again later, the previous impact can cause your
bicycle to break at a much lower load.
A Bicycle Cannot Protect You
in an Accident
Bicycles are not designed to withstand every
situation. In a crash or impact, it is not uncommon
for the bicycle to have damage and for you to fall.
If you fall, your bicycle can not prevent injury. Cars
have bumpers, seat belts, air bags, and crumple
zones. Bicycles do not, so even a small crash at
slow speed can cause injury or death.
Think Safety
Always “Think Safety” and avoid dangerous
situations, which are usually obvious. But not
all dangerous situations are obvious. Many of
those are shown in this manual; read at least
Chapter 1 before you ride.
Some of the high-risk stunts and jumps seen in
magazines or videos are very dangerous; even
skilled athletes get severe injuries when they
crash (and they do crash).
Changes to Your Bicycle
Can Make it Unsafe
Each and every part of your new bicycles has
been carefully chosen and approved. The
safety of accessory or replacement parts, and
especially how those parts attach and interface
with other parts of the bicycle, is not always
apparent. For this reason, you should only
replace parts with original equipment or parts
that are approved. If you are not sure what
parts are approved, ask your dealer.

Bicycle Type and
Use Condition
There are many types of bicycles. Each bicycle
type is made for a specified use, or Use
Condition. If your use of a bicycle applies more
stress than the limit of its use condition, this
could cause breakage of the bicycle (or a part of
the bicycle).
This section shows the Use Condition for different
types of bicycles. If you are not sure of what type
of bicycle you have, speak to your dealer.
Child Bicycle
A bicycle made for a child. A child should
not ride without the supervision of a parent.
Children should not ride near slopes, curbs,
stairs, drop-offs, or pools; or areas that
automobiles use:
• Maximum saddle height of 680 mm
• Usually a bicycle with 12”, 16”, or 20” wheels;
or a child’s tricycle
• No quick-release wheel attachment systems
• Weight limit of rider: 80 lbs (36 kg)
Condition 1
A bicycle made to ride on a paved surface
where the tires are always on the ground:
• Road bicycle with drop-type handlebar
• Triathlon, time trial, or speed bicycle
• Tandem
• Cruiser with large, 26” tires and swept-back
handlebar
• Pedelec electric-assist bicycle
• Weight limit of rider: 275 lbs (125 kg);
Tandem: 550 lbs (250 kg);
Pedelec: 300 lbs (136 kg)
Condition 2
A bicycle made to ride on Condition 1, plus
smooth gravel roads and groomed trails with
low-angle grades where the tires are always on
the ground:
• Hybrid bicycle with 700c wheels, tires wider
than 28c, and flat handlebars
• City bicycle: hybrid with special equipment
such as fenders or a light
• Cyclocross bicycle: drop-type handlebar,
knobby 700c tires, and cantilever
or disc brakes
• Mountain bike with 24” wheels
• Weight limit of rider: 300 lbs (136 kg)
24” wheel mountain bike: 175 lbs (80 kg)

Chapter 1: Guide to Safe On-and-Off Road Operation 2
Condition 3
A bicycle made to ride on Conditions 1 and 2, plus
rough trails, small obstacles, and smooth technical
areas, and also areas where tires momentarily are
not on the ground; NOT for jumps.
Any mountain bike that does not have rear
suspension is Condition 3. Any mountain
bike with short-travel rear suspension is also
Condition 3:
• “Standard,” “race,” or “cross-country” mountain
bike with wide, knobby 26” or 29” tires
• Short-travel rear suspension (3”/75 mm or less)
• Weight limit of rider: 300 lbs (136 kg)
Condition 4
A bicycle made to ride on Conditions 1, 2, and
3; plus rough technical areas, obstacles of
moderate height, and small jumps:
• “Heavy-duty,” “trail,” or “all-mountain”
mountain bike with wide, knobby 26” or 29”
tires
• Medium-travel rear suspension (4”/100 mm
or more)
• Weight limit of rider: 300 lbs (136 kg)
Condition 5
A bicycle made to jump, ride at high speeds,
ride aggressively on rougher surfaces, or
complete jumps on flat surfaces.
This type of use is very dangerous and puts
large forces on a bicycle. Large forces can apply
dangerous stress to a frame, fork, or the parts.
If you ride in Condition 5 terrain, you should
practice safety precautions such as more
frequent bicycle inspections and more frequent
replacement of equipment. You should also
wear comprehensive safety equipment such as
a full-face helmet, pads, and body armor.
• “Freeride” or “jumping” bicycle with heavy-
duty frames, forks, and components
• Long-travel rear suspension (7”/178 mm or
more)
• Weight limit of rider: 300 lbs (136 kg)
WARNING: If your use of a bicycle
applies more stress than the Use
Condition for which it is intended, the
bicycle or its parts can have damage
or break. A bicycle that has damage
could decrease your control and cause
you to fall. Do not ride in Use
Conditions that apply more stress
than the limits of the bicycle. If you
are not sure of the limits of the
bicycle, speak to your dealer.

Chapter 1: Guide to
Safe On-and-Off Road
Operation
Before a First Ride
Make Sure Your Bicycle is the Correct Size
Your dealer will help you find a bicycle
that has the correct dimensions for your
body. There should be at least 1” (25 mm)
clearance between the top tube and you
when you stand over your bicycle (Figure 1).
For a mountain bicycle, we recommend 2-3”
(50-75 mm) clearance.
You can adjust the saddle and handlebar to offer
the best comfort and performance. Before you
make these adjustments, refer to Chapter 3.
Know How Your Bicycle Operates
The properties of your bicycle, if not used
correctly, can decrease your control of the bicycle.
Before you ride fast or in conditions that are a
problem, learn the operation and performance
of all the mechanisms of your bicycle, especially
brakes and steering components. As an example,
“aero-bars” can make steering and braking
difficult. Practice the use of your bicycle at slower
speeds in a flat, empty parking area. Repeat this
step after any change to your bicycle.
If your bicycle does not operate as necessary,
or if different parts are necessary for the safe
operation of your bicycle, speak to your dealer.
Learn the Power of Your Brakes
The power of bicycle brakes changes with the Use
Condition of the bicycle. If you think it is necessary
for your bicycle to have more—or less—power to
stop, speak to your dealer about brake adjustments
or other brake options for your bicycle.
Chapter 1: Guide to Safe On-and-Off Road Operation
WARNING: If you do not use the
brake system correctly or you apply
too much force with the front-wheel
brake, the brakes could decrease your
control and cause you to fall. Practice
to correctly apply your brakes as
shown in this manual.
Prevent Toe-clip Overlap
Some modern, high-performance bicycles,
especially smaller sizes, use a short-wheelbase
design with the front wheel close to the pedals.
Increasing the distance between the front
wheel and pedals could place the handlebar
too far away or make the steering unwieldy. On
bicycles where this distance is short, when the
handlebar is turned during very slow speeds
your foot or toe-clips could overlap or touch the
front wheel or fender (Figure 2).
This overlap is affected by the size of your feet,
the length of the crankarms, and the pedals
you choose. At usual speeds, the handlebar
does not turn sufficiently for overlap to occur.
When you ride slowly, do not pedal when the
handlebar is turned.
WARNING: If your foot or toe-clip
touches the front wheel or fender,
toe-clip overlap could decrease your
control and cause you to fall. Do not
pedal when you turn at slow speed.

Checklist: Check Before Each Ride
This is not a full maintenance program.
Examine the Frame and Fork
Before and after each ride, examine all of your
bicycle for signs of fatigue stress:
• Dents • Cracks
• Scratches • Deformation
• Discoloration • Unusual noises
Bicycles are not indestructible, and their parts
will not last forever. If your use of a bicycle
increases the forces on it through hard riding,
difficult conditions, or increased mileage, you
should replace your bicycle or its parts more
frequently than riders who ride less or ride
smoothly and carefully. The safe life of a part
is determined by its construction, materials,
use, maintenance, rider weight, speed, terrain,
maintenance, and environment (humidity,
salinity, temperature, etc.)—so it is not possible
to give an accurate timetable for replacement.
If you are not sure if you should replace a part,
speak to your dealer.
A major impact is anything that causes you
to fall from your bike. It is not uncommon in
a major impact for the bicycle or its parts to
have damage. A minor impact, where you hit an
obstacle without falling from your bike, can still
place high stresses on your bicycle. After any
impact, if your bicycle behaves in an unusual
manner or you hear a noise, immediately stop
the bicycle and identify the problem. Always
inspect the bicycle thoroughly before riding the
bicycle again.
In some cases, a lighter frame or part
has a longer life than heavier ones. But
better maintenance, more frequent
inspections, and more frequent replacement
are necessary for light-weight, high-
performance bicycles and parts.
If Your Frame or Fork has a Problem,
Stop Your Bicycle
Frame problems are not common, but as an
example, some riders could get a “shimmy” or
“harmonic oscillation” or “frame wobble” at
some speeds. If you get a shimmy or any other
problem, decrease your speed immediately and
do not ride the bicycle. Transport your bicycle
directly to a dealer for inspection and repair.
FIGURE 2:
Toe-clip overlap
WARNING: A frame or fork problem
could decrease your control and cause
you to fall. If your bicycle gets a
shimmy or any other problem,
decrease your speed immediately.
Transport your bicycle to your dealer
for inspection and repair.
Examine Your Bicycle Before Each Ride
The checklist that follows shows critical areas
for you to examine. If a part of your bicycle
does not have the correct function, use the
instructions in this manual to repair your
bicycle or transport your bicycle to your dealer
for repair. Do not ride a bicycle with a part that
is damaged; replace the part.
WARNING: A bicycle that does not
operate correctly can decrease your
control and cause you to fall. Fully
examine all of your bicycle before
each ride, and do not ride your bicycle
until you correct any problem.

Chapter 1: Guide to Safe On-and-Off Road Operation5
WARNING: A carbon fiber part that
has damage can break suddenly,
causing serious injury or death.
Carbon fiber can conceal damage from
an impact or crash. If you suspect your
bicycle has had an impact or crash,
immediately stop the bicycle. Replace
the part before riding, or take the
bicycle to your dealer for service.
Carbon Fiber Composite
Pound for pound, carbon fiber is stronger that
steel or aluminum. But it behaves differently
when it is overloaded in an accident or impact.
An overloaded metal part will bend or deform
before it breaks, showing evidence of the load
(Figure 3). An overloaded carbon fiber part will
not bend or deform, so a damaged carbon part
(with reduced strength due to the damage)
may look normal—even after the same load
that bent the metal part. But when the sum of
the forces finally exceeds the strength limit of
the carbon fiber, the carbon fiber part breaks, it
does not bend (Figure 3).
In an accident or impact that does not break
the carbon fiber, the carbon fiber could have
internal or hidden damage but appear normal.
If that occurs, please carefully read these
instructions and examine the carbon fiber.
These tests are not conclusive: If you are not
sure a part is safe, replace it.
We offer a generous crash replacement program.
If you crash your carbon bicycle or part, visit your
dealer to learn more about this program.
To examine for surface problems
1. Clean the part fully with a moist cloth.
2. Look carefully for problems:
• Scratches or gouges • Discoloration
• Cracks • Loose fibers
• Other surface imperfections
To examine for a change of rigidity (flex test)
Do not ride, but use the part in the usual
manner while someone carefully examines
the part for movement or unusual noise. As an
example, sit on the saddle while someone looks
for unusual flex that would indicate a problem.
To examine for delamination (tap test)
1. Clean the part fully with a moist cloth.
2. With a coin, tap near the possible damage.
3. Listen carefully for variations in sound. Tap on
the part where it is in good condition (or use
a part that is almost the same). Compare the
sound. Anything unusual, especially a hollow
sound, indicates a problem.
Carbon Fiber Test
This section tells you how to examine carbon
fiber parts. A movie on the owner’s manual CD
(also on our web site) shows the tap test.

• The metal fork on
the left bent when
overloaded

Chapter 1: Guide to Safe On-and-Off Road Operation 6
Examine the Wheels
Make sure the wheels are straight. Turn the wheel
and examine the rim when it goes through the
brake-pads or the frame. The rim should not
wobble up and down or from side to side.
Make sure the wheels are attached correctly.
Lift your bicycle and hit the top of the tire
(Figure 4) with a solid blow. The wheel should
not come off, be loose, or move from side to
side. More tests are given in Chapter 3.
Your bicycle may use one or more systems to
attach the wheels to the frame: threaded axle
nuts, a lever-actuated quick-release mechanism
(Figure 5), or a thru-axle. For instructions about
adjustment and closure of the wheel attachment
devices on your bicycle, see Chapter 3.
WARNING: A wheel attachment
device that is not correctly adjusted
and closed can allow the wheel to be
loose or come off, decrease your
control, and cause you to fall. Make
sure the wheels are correctly attached
before you ride your bicycle.
Examine the tire inflation. Inflate the tires to
the air pressure recommended on the sidewall
of the tire.
Examine the Brakes
Use the inspection instructions for the type of
brakes on your bicycle:
WARNING: A brake system that has
damage or is not adjusted correctly
could decrease your control and cause
you to fall. Make a full inspection of
the brakes before each ride. If your
brakes do not operate correctly, do
not ride your bicycle. Adjust the
brakes or transport your bicycle to
your dealer for repair.
Hand-Rim Brake: a cable connects a hand lever
to the brake. The lever causes the brake-pads
to apply pressure to the rim.
Pull the brake-lever to make sure the brake
moves freely and stops your bicycle. If the brake-
lever can be pulled to the handlebar, the brake is
too loose. When the brakes are not applied, the
brake-pads should be 1 to 2 mm from the rim. If
the brake-pads are too near the rim, the brake is
too tight. The brake-pads should be in alignment
with the rim surface (Figure 6).

Chapter 1: Guide to Safe On-and-Off Road Operation7
Disc Brake: a cable or hydraulic hose connects
a hand lever to the brake. The lever causes the
brake to apply pressure to a disc attached to
the wheel hub.
Examine the Handlebar and Stem
Make sure the stem is in alignment with the front
wheel and correctly attached to the fork and
handlebar. To examine the attachment to the
fork, try to turn the handlebar from side to side
while you hold the front wheel between your
knees (Figure 8). To examine the connection
of the handlebar, try to twist it in the stem. The
handlebar should not move or be loose. Make
sure that no cables are pulled or caught on your
bicycle when you turn the handlebar.
Make sure the handlebar plugs are correctly put
into the two ends of the handlebar.
Examine the Saddle and Seatpost
Make sure the saddle is correctly attached. Try
to turn the saddle and seatpost in the frame,
and try to move the front of the saddle up and
down. The saddle should not move or be loose.
CAUTION: A disc brake and disc
gets very hot during use and could
burn skin. Also, the disc edges can be
sharp and could cut skin. Do not touch
the disc or disc brake when the disc
turns or when it is hot.
Pull the brake-lever to make sure the brake
moves freely and stops your bicycle. If the brake-
lever can be pulled to the handlebar, the brake is
too loose. When the brakes are not applied, the
brake-pads should be 0.25-0.75 mm away from
the disc. If the pads are too near the disc, the
brake is not in alignment or it is too tight.
Internal Hub Brake: a cable connects the
brake-lever to a mechanism in the hub.
WARNING: An internal hub brake
gets very hot during use and could
burn skin. Do not touch the hub or
cooling fins when hot.
FIGURE 7:
Test for chain tension
FIGURE 8:
Function test for the
handlebar and stem
If more than 5/8” (15 mm) of brake-lever
movement is necessary to stop your bicycle,
the brake is too loose. If less than 7 mm of
lever movement stops your bicycle, the brakes
are too tight.
Coaster Brake: when you move the pedals to
the rear, the brake engages.
The brake should engage before the crankarms
turn 60 degrees (1/6 turn). The chain operates
the brake, so make sure the chain can not come
off. There should be between 1/4-1/2” (6-12
mm) total vertical movement of the chain
(Figure 7).

Chapter 1: Guide to Safe On-and-Off Road Operation 8
Examine the Suspension
Adjust your suspension for your use, and
make sure that no suspension component can
“bottom-out,” or be fully compressed.
Examine the Lights and Reflectors
Make sure the lights operate correctly and
that batteries are charged. If the lights use a
dynamo, make sure the dynamo is mounted
correctly and all attachment hardware is tight.
Make sure all reflectors are clean and in their
correct position.
Some countries, areas. or governments have
specific requirements for lights, such as colors or
types. Check before traveling with your bicycle.
Rules to Ride Safely
Know and Obey Local Bicycle Laws
Most state and local areas have special laws
for bicycle riders, and you should obey the
laws. The necessary items such as lights and
reflectors change between areas. To learn
what is necessary, speak to the local bicycle
clubs or your Department of Transportation
(or the equivalent).
These are some of the more important rules for
when you ride:
• Use correct hand signals.
• Ride one at a time when you ride with other
bicycle riders.
• Ride on the correct side of the road; Do not
ride in the opposite direction of traffic.
• Ride defensively; be prepared for all
situations. A bicycle rider is hard to see, and
many drivers do not know the rights and
special considerations of a bicycle rider.
Look for Cars, Pedestrians,
and Other Obstacles
Look for potholes, drain grates, soft or low
shoulders, and other deviations which could
cause an impact to your wheels or cause the
wheels to slide. When you go across railroad
tracks or drain grates, ride carefully at a 90°
angle (Figure 9). If you are not sure of the
surface conditions, walk with your bicycle.
WARNING: A bicycle without
correct lights and reflectors might be
difficult for other people to see, and
you might not be able to see. If you
can not see, or other people can not
see you, you could have an accident.
Use a front light, a rear light, and
reflectors when you ride in low
visibility conditions.
FIGURE 9:

Chapter 1: Guide to Safe On-and-Off Road Operation9
If a car suddenly moves into your lane or
someone opens the door of a parked car, you
could be in a bad accident. Attach a horn or bell
to your bicycle. Use it to tell other people that
you are near.
Wear a Helmet and Bicycle Clothing
Wear a helmet that complies with CPSC or CE
safety standards (Figure 10); it can prevent injury.
Remove your helmet when you are not on your
bicycle; if the helmet is caught, you could choke.
Wear bicycle clothing, eye protection, and
gloves. Do not wear clothing that is loose; it
could get caught in the chain or the wheels.
Also wear light, bright, and reflective clothing to
make you more easy to see, especially at night.
Ride Safely in Wet Weather or Wind
No brakes stop as effectively in wet weather as
they do in dry weather. Even with brakes that
are correctly adjusted and serviced, more lever
pressure and longer distances are necessary to
stop in wet weather.
Wet weather causes decreased traction. The
road surface can become slippery and ordinary
objects can become treacherous, such as
wet leaves, painted crosswalks, or manhole
covers. When wet surfaces freeze, traction is
decreased further. Strong winds can make a
bicycle turn without your control.
When you ride in wet weather, a wet tire can
cause a malfunction of a dynamo (generator
light). Do not ride in wet weather when visibility
is decreased.
FIGURE 10:
Wear a bicycle helmet
when you ride
WARNING: Wet or inclement
weather can make a bicycle difficult to
control. Decrease your speed and use
extra caution, or use other types of
transportation.
Make Sure Other People Can See You
Your bicycle has a full set of reflectors. Make
sure the reflectors are clean and in the correct
position. As useful as these reflectors are, they
do not help your vision. They do not make you
easy to see unless light is pointed at them. You
should see and be seen. If you ride at dusk, at
night, or in low-visibility conditions, speak to
your dealer to find equipment or materials to
help your vision and make you more easy to see.
WARNING: When you ride in
low-visibility conditions such as fog,
dusk, or night, you might be difficult
to see, which could lead to a collision.
Use a front light and rear light when
you ride in conditions with low light or
low visibility.
Think About Safety When You Ride
You can prevent many bicycle accidents if you
think about safety. Here are some examples:
• Do not ride ‘no hands.’
• Do not ride with loose objects attached to
the handlebar or other part of your bicycle.
• Do not ride while intoxicated or while you use
medications which can make you drowsy.
• Do not ‘ride double.’
• Ride carefully when off-road. Ride only on
the trails. Do not ride over rocks, branches,
or depressions. When you ride near a

Chapter 1: Guide to Safe On-and-Off Road Operation 10
Riding instructions
Use Your Brakes Carefully
Always ride with a safe distance between you
and other vehicles or objects; use your brakes.
Adjust distances and brake forces for the
conditions in which you ride.
If your bicycle has a “coaster brake” activated
by the pedals, you apply the brake by pedalling
backwards. To apply the greatest force, the
crankarms should be horizontal when you apply
the brake. The pedal will rotate before the brake
starts to work, so start to apply the brake with
the rear pedal slightly higher than this position.
If your bicycle has two hand brakes, apply
the two brakes at the same time. Over-use or
incorrect use of a front-wheel brake could cause
the rear wheel to lift from the ground which
could decrease your control (Figure 11).
descent, decrease your speed, move your
weight low and to the rear, and use the rear
brake more than the front.
• Do not ride abusively. Ride in the Use
Conditions specified for your bicycle type.
• Do not ride too fast. Higher speeds cause
higher risks. At higher speeds, it is more
likely that wheels will slide, or that a small
bump can cause an impact to your frame
or fork. Higher speeds make larger forces
if a crash occurs. Control your bicycle at
all times.
WARNING: You add to your risk of
injury when you do not use your
bicycle correctly:
• Jump your bicycle
• Ride over sticks or debris
• Do bicycle stunts
• Ride in severe off-road terrain
• Ride fast, in competition, or
“downhill”
• Ride in an unusual manner
Each of these uses adds to the stress
on each part of your bicycle. High
stress can cause the frame or part to
break and increases your risk of injury.
To decrease your risk of injury, use
your bicycle correctly.
WARNING: Training wheels prevent
the regular lean of a bicycle when the
rider makes a turn. If the child turns
too quickly, the bicycle can fall. With
training wheels, do not permit children
to ride fast or turn suddenly.
FIGURE 11:
Do not over-use the
front-wheel brake; the
rear wheel can lift and
cause you to lose control
WARNING: Brake force applied to
the front-wheel suddenly or too fully
could lift the rear wheel off the ground
or cause the front wheel to slide out
from below you. This could decrease
your control and cause you to fall.
Apply the two brakes at the same time
and move rearward on your bicycle.
For children, the limit of speed is much lower.

Chapter 1: Guide to Safe On-and-Off Road Operation11
We make bicycles so that the left brake-lever
controls the front-wheel brake. To change your
bicycle so that the right brake-lever controls the
front-wheel brake, see Chapter 3.
Many models of modern brakes are very powerful;
they are made to stop a bicycle in wet or muddy
conditions. If you think your brakes are too
powerful, transport your bicycle to your dealer for
adjustment or replacement of the brake system.
Change Gears Correctly
You can change to the gear combination that
is most comfortable for the conditions, a gear
that lets you to pedal at a constant rate. Gear
change systems are of two types: derailleur
(external) and internal.
To change gears with a derailleur
The left shift-lever controls the front derailleur and
the right shift-lever controls the rear derailleur.
Use only one shift-lever at a time. Change gears
only when the pedals and chain move forward.
When you change gears, decrease the force on
the pedals to change gears quickly and smoothly,
to decrease chain and gear wear, and to prevent
bent chains, derailleurs, or chainrings. Do not
change gears when you ride over bumps; the
chain could miss a gear or fall off.
With modern, indexed gear-change systems, a
movement of the shift-lever from one position
to the other position (or movement of the shift-
lever to the “shift” position) will promptly move
the chain to a different gear.
Bicycles that have STI road shift-levers and
three chainrings can change front gears better
if you “hold” the lever for a moment before
you release the left shift-lever. This is most
important when you change gears from the
smallest chainring to the middle chainring.
To change gears with internal gears
To change gears, move the pedals to the rear
or do not move them. If you must change gears
while you pedal, decrease your pressure on the
pedals. Too much tension on the chain prevents
the correct operation of the gear change
mechanism and could damage the mechanism.
Use Pedal Systems Carefully
If your feet are secured to the pedals, the
connection can allow you to pedal more
efficiently, apply greater power to the pedals,
or increase your control of the bicycle. Some
bicycles are equipped with one of these systems:
• Toe-clips and straps attach your feet to the
pedals with a strap with a locator that wraps
up and in front of your toes.
• Clipless pedals use a spring-loaded mechanism
to engage a cleat, a small plate attached to the
bottom of a special cycling shoe.
If you choose to ride with one of these systems,
practice entry and exit from the pedal before
you ride. Keep the pedals and your shoes
clean and free of debris that could interfere
with the pedal system. Make sure any release
mechanism operates correctly, and adjust it for
your riding.
If you are not familiar with the pedals or the
correct procedures, read the information on the
Owner’s Manual CD or consult your dealer.
WARNING: A pedal system that
operates incorrectly could cause your
feet to become trapped or allow your
feet to release from the pedal
unexpectedly, causing you to lose
control. Make sure you are familiar
with the pedal system before riding,
and that the pedal system operates
correctly.

Safeguard Your Bicycle
Prevent Theft of Your Bicycle
Purchase and use a lock that resists bolt
cutters and saws. Do not park your bicycle
unless it is locked. Also, get a licence for your
bicycle from your local police department.
Write down your serial number
Write the serial number of your bicycle in the
front of this manual, and put the manual in a safe
location. Then, complete our on-line registration;
we will keep the serial number on file.
Safely Park Your Bicycle
When you complete a ride, put your bicycle in
a location where it will not be an obstruction.
Make sure it can not fall. Do not put down
your bicycle on its derailleurs, because you
could bend the rear derailleur or get dirt on the
drivetrain. Do not let your bicycle fall, because
this could cut the handlebar grip or cause
damage to the saddle. Incorrect use of a bicycle
rack could bend your wheels.
Park your bicycle carefully
When your bicycle is not in use, park it where
it has protection from dangerous conditions.
Do not park your bicycle near electric motors;
ozone from motors can cause damage to rubber
and paint. Rain or snow can cause the metal
on your bicycle to corrode. Ultraviolet radiation
from the sun can fade the paint or crack the
rubber or plastic on your bicycle.
Before you put away your bicycle for an extended
time, clean and service it and apply frame polish.
Hang your bicycle off the ground with the
tires at approximately half the recommended
inflation pressure. Before you ride your bicycle
again, be sure it operates correctly.
WARNING: Any modification can
make your frame, fork, or part unsafe.
Do not sand, drill, file, remove
redundant retention devices, install
incompatible forks, or make other
modifications. A component that is not
approved or assembly that is not
correct can put high stress on your
bicycle or components. A frame, fork,
or component with modifications could
decrease your control and cause you to
fall. Before you add an accessory to
your bicycle or change a part of your
bicycle, speak to your dealer.
Include Repair Items when You Ride
When you ride, include a pump, a spare inner
tube, patch kit, and tools so you can repair your
bicycle if it has a flat tire of other mechanical
problem. If you ride at night, include spare
bulbs and batteries for your lights.
Only Install Compatible Accessories
Not all accessories are compatible or safe, so
only add accessories that have the approval
of the manufacturer. As an example, a child
carrier puts weight high on the bicycle. This
can make your bicycle less stable. Although
some child carriers are compatible with some
of our bicycles, always check with your dealer
before making any change to your bicycle.
As another example, clamping anything on a
carbon part can weaken or damage the part.

Chapter 2: Maintenance13
Chapter 2: Maintenance
This maintenance schedule is based on usual
use. If you ride your bicycle more than average,
or in rain, snow, or off-road conditions,
do maintenance on your bicycle more
frequently than the schedule recommends.
If a part malfunctions, examine and repair it
immediately, or speak to your dealer. If a part
has wear or damage, replace it before you ride
your bicycle again.
After initial use, new bicycles should be
examined. As an example, cables stretch
through use, and this can affect the operation
of the shifting or brakes. Approximately two
months after you purchase your new bicycle,
have your dealer fully examine your bicycle.
You should have your dealer fully service your
bicycle each year, even if you did not ride it much.
Tools for Bicycle Maintenance
• Torque wrench with lb•in or N•m gradations
• 2, 4, 5, 6, 8 mm allen wrenches
• 9, 10, 15 mm open-end wrenches
• 15 mm box end wrench
• Socket wrench, 14, 15, and 19 mm socket
• T25 Torx wrench
• No. 1 phillips-head screwdriver
• Bicycle inner tube patch-kit, tire-pump with
gauge, and tire levers
• Special high-pressure air-pump for a rear
shock or a suspension fork
Not all these tools are necessary for all bicycles
Clean Your Bicycle
If your frame or a component is not clean, clean
it with a soft, moist cloth and bicycle cleaner or
a solution of dish soap and water. Do not use
industrial solvents or harsh chemicals. They can
cause damage to the paint or moving parts.
Each three months, clean and polish the frame
finish. Some finishes do not require polish. If
you are not certain, consult your dealer.
Avoid Incidental Damage
to Your Bicycle
Do not clamp the frame during
transportation or repair
Do not clamp the bicycle frame. This can cause
damage to the paint or even dent, crush, or
break the light-weight frame-tubes used in
high-performance bicycle frames.
When holding the bicycle for repairs, clamp
the seatpost. When holding the bicycle for
transportation on a motor vehicle, clamp the
bicycle by the wheels or fork tips.
Prevent damage to your bicycle
when you ship it
If you need to package your bike for travel,
always use a hard case or carton that will
protect your bicycle. Attach pads to all the
frame and fork tubes, and use a rigid block to
protect the fork tips and maintain structural
support of the fork blades. If the bicycle is not
packaged correctly, it could be easily damaged
in transit. If you are not sure, ask your dealer to
package your bicycle for you.

Chapter 3: Adjustment15
Handlebar
You hold the handlebar to steer the bicycle. Its
position is important for control and comfort.
To adjust the angle of the handlebar
1. Decrease the tightness of the handlebar-
clamp bolt(s) on the stem (Figure 12 and
Figure 13).
2. Move the handlebar. Make sure it is in the
center of stem.
3. Tighten the handlebar-clamp bolt(s) on your
type of stem:
• Welded stems: 100-120 lb•in (11.3-13.6 N•m)
• Forged stems: 150-180 lb•in (17-20.3 N•m)
Stem
The stem connects the handlebar to the fork
There are two types of stems:
• Direct-connect (Figure 12)
• Quill-type (Figure 13)
Chapter 3: Adjustment
This chapter gives instructions for adjustment
of the parts of a bicycle. They are written for a
person familiar with the basics of mechanics
and with proper tools. Because your safety
depends on the correct maintenance of your
bicycle, we recommend you have your dealer
service your bicycle. After a repair, examine
your bicycle as shown in the “Before Each Ride”
checklist in Chapter 1.
A Word about Torque Specifications
Torque is a measure of the tightness of a screw
or bolt. Use a torque wrench to make sure you
do not apply too much torque, which can cause
damage or break the part. However, a fastener
that is too loose can also cause damage.
After you use the torque wrench, examine
the function of the part with the tests in
this chapter. If a part does not have the
correct function when it is tightened to the
recommended torque, transport your bicycle to
your dealer for repair. If your bicycle has parts
with fasteners not listed in this manual, see the
more extensive information on the Owner’s
Manual CD, or consult your dealer.

WARNING: A bicycle that
malfunctions could decrease your
control and cause you to fall. Fully
examine all of your bicycle before each
ride. If there is a problem, do not ride
your bicycle: repair your bicycle or
transport it to your dealer for service.
WARNING: Incorrect torque can
cause damage or break a part. Use a
torque wrench to correctly tighten a
part, or transport the bicycle to your
dealer for service.
WARNING: Overtightening of stem
bolts can cause damage to the steerer
of the fork, possibly causing it to break.
If the steerer breaks, you could fall.

Chapter 3: Adjustment 16
To align or adjust a quill-type stem
To adjust the height of the adjustable-rise stem
in Figure 13, first change the stem angle (see
the subsequent section), which gives access to
the expander bolt.
1. Decrease the tightness of the expander bolt
two to three turns.
2. The stem is held by the stem wedge. To
decrease the tightness of the stem wedge,
tap the top of the expander bolt with a mallet
that has a wood or plastic face.
3. Adjust the handlebar to the necessary height,
but the minimum-insertion mark must be
in the frame (Figure 13). A minimum of 23 /4 ”
(70 mm) of the stem quill should always be
in the frame.
4. Tighten the expander bolt to 120 lb•in
(13.6 N•m).
FIGURE 14:

WARNING: A quill stem that is too
high can cause damage to your bicycle,
decrease your control, and cause you to
fall. Make sure the minimum-insertion
mark (Figure 14) is in the frame.
Minimum spacers with a direct-connect stem
On a bicycle with an aluminum steerer, there
should be at least one 5mm spacer under
the direct-connect stem. On a bicycle with a
carbon steerer, there should be at least one
5mm spacer below the stem and also one 5mm
spacer above the stem (Figure 15).
FIGURE 15:
Required spacers above
and below a direct-
connect stem
WARNING: Incorrect or missing
spacers can cause damage to the
steerer of the fork, possibly causing it
to break. If the steerer breaks, you
could fall.
To align a direct-connect stem
1. Decrease the tightness of the steerer-clamp
bolts two to three turns.
2. Align the stem with the front wheel.
3. Tighten the steerer-clamp bolts to
100-120 lb•in (11.3-13.6 N•m).
To adjust the height of a direct-connect stem
To adjust the height of the handlebar with a
direct-connect stem, the headset bearing must
be adjusted. Special tools and training are
necessary for bearing adjustment, so only your
dealer should do this.
To change the angle of an adjustable-rise stem
1. Decrease the tightness of the angle
adjustment bolt (Figure 13) until the stem
angle can be changed.
2. Move the stem to the necessary angle.
3. Tighten the angle-adjustment bolt to
150-170 lb•in (17-20.3 N•m).
