CHAPTER 1: GUIDE TO SAFE ON-AND-OFF ROAD OPERATION
Bicycle type and use classification
Riding a bicycle in a manner beyond, or more severe than, its intended use can cause
the bicycle or part of the bicycle to fail. The following information explains the type of
riding intended for different types of bikes. Read the safety information in Chapter 1 for
further details.
Condition 1
Bikes designed for riding on a paved surface where the tires do not lose ground
contact.
Condition 1 bike types
• Drop-type handlebars including touring bikes, but not cyclocross bikes
• Triathlon, time trial, or speed bikes
• Tandems of any design
• Cruisers with wide, 26" tires and swept-back handlebar
• Any bike that folds
• Weight limit: 275 lbs (125 kg); Tandems: 550 lb (250 kg)
Condition 2
Bikes designed for riding Condition 1, plus smooth gravel roads and improved trails
with moderate grades where the tires do not lose ground contact.
Condition 2 bike types
• Hybrid bikes with 700c wheels, tires wider than 28c, and flat handlebars
• City bikes- specially-equipped hybrids
• Cyclocross bikes- with drop-type handlebars, knobby 700c tires, and cantilever or
disc brakes
• Weight limit: 300 lbs (136 kg)

Figure 1- Minimum
stand-over height
A = 1" (25 mm) for most
bicycles
2-3" (50-75 mm) for
mountain bicycles
Mis-use of the braking system,
including over-use of the front
brake, can cause you to lose
control and fall. Avoid improper
braking by understanding and
practicing proper application of
your brakes as explained in this
manual.
Contact between your foot or
toe-clip and the front wheel or
fender can cause you to lose
control and fall. Avoid pedaling
when turning at slow speed.
Before a first ride
Make sure the bicycle fits
There should be at least 1” (25 mm) clearance between the top
tube and the rider when standing over the bicycle (Figure 1).
For mountain bikes, 2-3” (50-75 mm) clearance is
recommended.
The seat and handlebar may be adjusted to offer the best
comfort and performance. Before making these adjustments,
refer to Chapter 3.
Know how the bicycle performs
The features of your bicycle, if misused, may cause you to lose
control of the bike. Before riding fast or in more difficult
conditions, learn the function and performance of all the
mechanisms of your bike by riding at slower speeds in a flat,
empty parking lot.
If you want your bicycle to perform differently, or if you have special needs that require
different parts for the safe operation of your bike,
consult your bicycle dealer.
Learn the power of your brakes
The stopping power on bikes varies according to the
intended use of the bike. If you would like your bike to
have more, or less, stopping power, consult your
dealer about brake adjustments or other brake
options for your bicycle.
Avoid toe-clip overlap
When riding slowly, do not pedal if the handlebar is turned. It may be possible, at very
slow speeds, when the handlebar is turned, for your foot or toe-clips to contact the
front wheel or fender (Figure 2). At normal riding speeds, the handlebar does not turn
enough for this to occur.

A shimmy, or steering wobble,
can cause you to lose control
and fall. If you experience a
shimmy, slow down
immediately. Take your bicycle
to your dealer for inspection
and re
p
air.
A bicycle that does not work
properly can cause you to lose
control and fall. Inspect the
entire bicycle thoroughly before
every ride, and do not ride it
until any problem has been
corrected
Figure 3: -wheel quick
release
A wheel attachment device that
is not properly adjusted and
closed may allow the wheel to
be loose or come off
unexpectedly, causing you to
lose control and fall. Make sure
the wheels are properly
attached before riding the bike.
Stop riding if you have frame problems
Occasionally riders experience problems with their
frame or fork. If a frame or fork has any problem, do
not ride the bicycle.
As an example, in very rare cases, some riders may
experience
a “shimmy” or “harmonic oscillation” or “frame
vibration” at certain speeds. If you are experiencing
a shimmy, slow down immediately. Take your
bicycle directly to a dealer for inspection and repair.
Check the bike before every ride
Before every ride, inspect the bike with the following check list. If any part of the
bicycle fails the inspection, repair the bicycle by following the information provided by
this manual, or take the bike to your dealer for service. Never ride a bike with a
damaged part; have it replaced.

Check the wheels
Check that the wheels are straight. Spin each wheel and watch the rim as it passes
through the brake pads or the frame. If the rim wobbles up and down or from side to
side, repair the wheel.
Check that the wheels are
properly attached. Bicycle
wheels are attached by several
systems: threaded axle nuts, a
quick-release where a lever-
actuated wheel retention
mechanism (Figure 3) allows the
wheel to be installed and

ever ride a bike if you are not
certain the brakes are working
properly, or you if suspect a
problem with the brake cables
or hydraulic hose.
Malfunctioning brakes can
cause you to lose control and
fall. Inspect the brakes
thoroughly before every ride. If
your brakes are not working
properly, re-adjust them or take
the bike to your dealer for
service.

threaded through the ends of the frame or fork. For information about adjustment and
closure of the wheel attachment devices on your bicycle, see Chapter 3.
Test for proper wheel attachment. Pick up the bike and sharply hit the top of the tire
(Figure 4). The wheel must not come off, be loose, or move from side to side. Further
tests are provided in

Check the tire inflation
Inflate the tires to the air pressure recommended on the tire sidewalls.
Check the brakes
Follow the inspection instructions for the type of brake
on your bike:
Hand-rim brake- a hand lever connected to the brake
by a cable causes the brake pads to squeeze the rim.
When the brakes are not applied, the brake pads
should be 1 to 2 mm from the rim.
Squeeze each brake lever toward the handlebar to
make sure the brake moves freely and stops the bike.
If the brake lever can be pulled to the handlebar, the
brake is too loose. If the brake pads are too close to
the rim, the brake is too tight. Brake pads should be
aligned with the rim surface (Figure 5).
Disc brake- a hand lever connected to the brake
by a cable or hydraulic hose squeezes a disc
mounted on the wheel hub.
Squeeze each brake lever toward the handlebar to
make sure the brake moves freely and stops the
bike. If the brake lever can be pulled to the
handlebar, the brake is too loose. The brake pads
should be 0.25-0.75 mm away from the disc when
the brakes are not applied. If the pads are too
close, the brake is too tight, or mis-aligned.


Check the seat and seatpost
Make sure the seat is secure by attempting to turn the seat and seatpost in the frame,
and attempt to move the front of the seat up and down. It should not move or be loose.
Check the lights and reflectors
Make sure the lights are functioning correctly and that any batteries are charged. If the
lights use a dynamo, make sure it is mounted correctly and all attachment hardware is
tight. Make sure reflectors are clean and in position.
Check frame, fork, and components
Carefully inspect your frame, fork, and components for signs of fatigue before and after
each ride. Regularly inspect your entire bicycle for signs of fatigue stress:
• Dents
• Cracks
• Scratches
• Deformation
• Discoloration
• Unusual noises
Even if you perform regular inspections, if you exceed the limit of strength of your
bicycle or a given part, it may fail if overloaded. After any high force load, thoroughly
inspect all the parts of your bike. High force loads include crashes, but you don't have
to crash to put a high force load on your bike. For example, hitting a large hole in the
road or a sharp bump such as a railroad track can put large forces on your bike.
The manner in which you ride will determine whether your bike and its parts will last. If
you ride hard or aggressively, you should replace the bike and/or its parts more often
than riders who ride smoothly or cautiously. There are many variables: weight, speed,
technique, terrain, maintenance, riding environment (humidity, salinity, temperature,
etc.), and the frame or part itself- so it is impossible to give a precise timetable for
replacement. If you aren't sure, ask your dealer. But as a rule, it is better to err on the
safe side and replace the bike or parts more frequently.

RULES FOR SAFE RIDING
Know and observe local bicycle riding laws
Most state and local areas have specific laws for cyclists, and you should follow them.
Local cycling clubs or your state’s Department of Transportation (or equivalent) should
be able to supply this information to you. The requirements
for items such as lights and reflectors change between areas, so check ahead.
These are a few of the more important rules of riding:
• Use proper hand signals.
• Ride single file when riding with other cyclists.
• Ride on the correct side of the road; never go against traffic.
• Ride defensively; expect the unexpected. A cyclist is hard to see, and many drivers
simply are not trained to recognize the rights and special considerations
of a bicycle rider.
Watch for cars, pedestrians, and other obstacles
Watch for and avoid potholes, drain grates, soft or low
shoulders, and other deviations which could impact your
wheels or cause them to slip. When crossing railroad tracks
or drain grates, do so carefully at a 90° angle (Figure 8). If
you are not sure of riding surface conditions, walk your bike.
If a car suddenly enters your lane, or someone unexpectedly
opens the door of a parked car, you could be involved in a
serious accident. Mount a horn or bell on your bicycle, and
use it to alert others of your approach.
Wear a helmet and proper cycling clothes
Wear a helmet that meets CPSC or CE safety testing
standards (Figure 9); it may help prevent injury.
Helmets should be removed when not riding the bicycle. If
the helmet is caught, stuck on, or stuck between objects, the
wearer could choke.
Wear protective clothing including helmet, eye protection,
and gloves. Avoid loose-fitting pants that could get caught in
the chain.
Also wear light, bright, and reflective clothing to make
yourself more visible, especially at night.
Change your riding to be safe in variable
conditions
Ride carefully in wet weather
No brakes, whatever their design, work as effectively in wet weather as they do in dry.
Even properly aligned, lubricated, and maintained brakes require greater lever pressure

- 11 -
and longer stopping distances in wet weather. Anticipate the extra distance it will take
to stop.
Wet weather causes reduced traction. Use slower cornering when traction is reduced,
such as when riding over wet leaves, painted crosswalks, or manhole covers.
When wet weather cools to below freezing, traction is reduced even further. In
addition, brakes may not work as well. Adjust your riding speed accordingly, or use
other forms of transportation.
When riding in wet weather, a dynamo (generator light) may not work properly. Avoid
riding in wet weather when visibility is reduced.
Strong winds can make a bicycle steer or turn unexpectedly. In windy conditions, slow
down or use other forms of transportation.
Be careful when riding in low light conditions.
Your bicycle is equipped with a full set of reflectors; keep them clean and in position.
As useful as these reflectors are, they do not help you see, nor do they help you be
seen unless light is directed on them. Use a working headlight and taillight when you
ride in poorly lighted or low visibility conditions. The important thing is to see and be
seen. If you do any amount of riding at dusk, at night, or in any poorly lighted
conditions, consult your dealer to find appropriate products to aid your vision and
make you more visible.
Do not use unsafe riding practices
Many cycling accidents could be avoided by using common sense. Here are a few
examples:
• Do not ride ‘no hands’.
• Do not ride with loose objects attached to the handlebar or any other part of the
bicycle.
• Do not ride while intoxicated or while using medications which might make you
drowsy.
• Do not ‘ride double’.
• Use special care when off-road riding. Ride only on the trails. Avoid rocks, branches,
or depressions.
When approaching a descent, reduce speed, keep your weight back and low, and use
the rear brake more than the front.
• Do not ride in an abusive manner; ride within the Use Classification for your type of
bicycle (see pages 1-2).
Bicycles are not indestructible. As with anything mechanical, every part of a bicycle
has a limited useful life due to wear, stress, and fatigue. Fatigue refers to a low-stress
force that, when repeated over a large number of cycles, can cause a material to fail or
break. The length of the life of a part varies according to its design, materials, use, and
maintenance. Although lighter frames or parts may, in some cases, have a longer life
than heavier ones, it should be expected that light-weight, high-performance bicycles
and parts require better care and more frequent inspections.

- 12 -
The following riding practices
increase your risk of injury:
• Jumping your bicycle
• Performing bicycle stunts
• Severe off-road riding
• Downhill riding
• Any abnormal bike riding
Each of these practices increases the
stress on every
part of your bicycle. Frames or parts
under high stress may fatigue
prematurely, causing them to fail and
increasing the risk of injury to the
rider. To decrease your risk of injury,
avoid these riding practices. Avoid
riding too fast.
A bicycle rider without proper lighting
and reflectors may not have good
vision and may not be visible to
others. Use front and rear bicycle
lights and reflectors when riding in
poor visibility conditions. Failure to do
so will increase your chances of being
involved in an accident in low light
conditions.
Avoid riding too fast
Higher speeds create higher risks and greater forces in the event of a crash. At higher
speeds, it is more likely that wheels will slip, or that a small bump can create a
significant impact to your frame or fork. Keep your bicycle under control at all times.
For children, the limit of speed for safe riding is much lower, so parents should strictly
enforce this rule.

- 13 -
Applying sudden or excessive
stopping force with the front-wheel
brake may cause the rear wheel to lift
off the ground, or the front wheel to
slip out from under you, which can
cause you to lose control and fall.
Apply both brakes at the same time,
and shift your weight backwards on
the bike while braking.
Riding instructions
Use your brakes carefully
Always keep a safe stopping distance between you and other vehicles or objects.
Adjust stopping distances and braking forces to suit riding conditions.
If your bike has two hand brakes, apply both brakes at the same time. Over-use, or
mis-use, of a front-wheel brake, such as using only the front-wheel brake in an
emergency, could cause the rear wheel to lift from the ground
which could cause you to lose control (Figure 10).
Bicycles are normally manufactured
with the left brake lever controlling the front-wheel brake. To
change so that the right lever controls the front-wheel brake,
see Chapter 3.
Many models of modern brakes are very powerful; they are
designed to stop a bike in wet or muddy conditions. If you feel
your brakes are too powerful for your riding needs, take your
bike to your dealer for adjustment or replacement of the
braking system.
Use good shifting techniques
Shifting gears allows you to choose the gear
combination most comfortable for riding
conditions, one that allows you to maintain a
constant rate of pedaling. Shifting systems are
of two types: derailleur
(external) and internal.
Shifting a bike with a derailleur
The left-hand shifter controls the front
derailleur and the right-hand shifter controls the
rear derailleur. Use only one shifter at a time.
Shift gears only when the pedals and chain are moving forward. When you shift,
reduce the force on the pedals to provide quicker and smoother shifting, to help avoid
excessive chain and gear wear, and to help avoid bent chains, derailleurs, and
chainrings. Avoid shifting when going over bumps; the chain may not shift properly or
may fall off.
With modern indexed shifting systems, a movement of the shifter from one position to
the next (or movement of the shifter to the "shift" position) should promptly move the
chain from one gear to the next. However, bikes equipped STI road shifters and triple
chainrings may shift better, particularly
when shifting from the smallest chainring to the middle, if you “hold” the lever for a
moment before letting go of the shifter.

- 14 -
Never modify your frameset or parts in
any way, including sanding, drilling, filing,
removing redundant retention devices,
installing incompatible forks, or by any
other method. Improper components or
improper assembly can place unknown
stress on your bike or components. An
improperly modified frame, fork, or
component can cause you to lose control
and fall. Before adding or changing any
part of your bike, consult your dealer.
TAKE CARE OF YOUR BIKE
Protect your bike when parking or storing it
Protect your bike from theft
Purchase and use a lock that is effective against bolt cutters and saws. Never leave
your bike unlocked while unattended.
Record and keep your serial number
Register your bicycle with your local police department. Complete our on-line warranty
registration; we will keep the serial number of your bike on file. Also, write the serial
number in the front of this manual, and keep the manual in a safe place.
Park your bike safely
When not riding, keep your bike in a place where it will be out of the way, and make
sure it cannot fall over. Do not lay the bike on its derailleurs, as you may bend the rear
derailleur or get dirt on the drivetrain. Don’t let the bike fall down, as this may cut the
handlebar grips, or tear the seat. Incorrect use of bike racks may bend your wheels.
Store your bike carefully
When not riding, keep your bike where it will be protected from rain, snow, sun, etc. Do
not store the bike near electric motors, as ozone from motors destroys rubber and
paint. Rain or snow may cause the metal on your bicycle to corrode. Ultraviolet
radiation from the sun may fade the paint, or crack any rubber or plastic on the bicycle.
Before storing your bike for an extended period of time, clean and lubricate it, and
polish the frame with frame polish. Hang the bicycle off the ground with the tires at
approximately half pressure. Before riding the bicycle again, be certain it is in good
working order.
Carry repair items
Carry a pump, spare inner tube, patch kit, and appropriate tools to keep your bicycle
running in the case of a flat tire of other
common mechanical problem. If you ride at
night, carry spare bulbs and batteries for
your lights.
Only install and use approved
accessories
Not all accessories are compatible or safe,
so only add accessories that are approved
by the manufacturer.
As an example, a child carrier places weight
high on the bike, affecting the stability of

- 15 -
the vehicle. Although most of our bikes can be fitted with a child carrier, the rider must
use extra caution to compensate for the decreased stability. The list of incompatible
parts is too long for this manual. If you are unsure whether a part is approved, consult
your dealer.
Keep the bike clean
If your frame or a component is dirty, clean it with a soft, damp cloth and bike cleaner
or a solution of dish soap and water. Use of industrial solvents or harsh chemicals for
cleaning may damage the paint.
Avoid clamping the frame during transportation or repair
Never clamp the bike frame by its finished or painted surfaces. This type of clamp this
may damage the paint or even dent, crush, or break the light-weight tubing used in
high-performance bicycle frames.
Protect your bicycle during shipping
If you have to ship your bike, make sure it is properly padded and protected to avoid
damage. Ask your dealer about supplies used to ship a new bike, such as a fork block.
Notice
Clamping devices used by work stands and car carriers can damage the finish on a
bike or even crush the tubing. When putting a bike in a repair stand, clamp the
seatpost. When carrying a bike in a car carrier, clamp the wheels and the fork tips.

- 16 -
CHAPTER 2: MAINTENANCE
Maintenance schedule
This maintenance schedule is based on normal usage. If you ride your bike more than
average, or in rain, snow, or off-road conditions, service your bicycle more often than
the schedule suggests. If any part appears to be malfunctioning, inspect and service it
immediately, or consult your dealer. If a part is damaged, replace it before riding the
bicycle again.
After initial break-in, new bikes should be checked for stretched cables and other
normal conditions. Approximately two months after purchasing your new bike, have
your dealer thoroughly inspect the bicycle.
All bikes should be thoroughly serviced once a year, even if they have not been ridden
much.

CHAPTER 3: ADJUSTMENT
This chapter lists instructions for adjustment of the parts of a bicycle. After any repair,
inspect the bike as explained in Chapter 1.
A Word About Torque Specifications
Torque is a measurement of the tightness of a
threaded fastener such as a screw or bolt,
determined by using a torque wrench. The
torque specifications
should be used to make sure you do not over-
tighten the fasteners. Applying more than the
recommended torque to a fastener does not
provide extra holding power, and may actually
lead to damage or failure of a part.
Always perform the simple function tests listed in this chapter to make sure a part is
properly tightened, whether or not the part was tightened with a torque wrench. If a
part fails inspection at the recommended torque, take the bike to your dealer.
Handlebar
To adjust the angle of the handlebar
1. Loosen the handlebar clamp bolt(s) on the
stem (Figures 11-12) just enough that the
handlebar can be rotated in the stem.
2. Position the handlebar to the desired angle,
making sure it is centered in the stem.
3. Tighten the handlebar clamp bolt(s) according
to stem type:
• Welded stems- 100-120 lb•in (11.3-13.6 N•m).
• Forged stems- 150-180 lb•in (17-20.3 N•m)
Stem
There are two types of stems:
• Direct-connect (Figure 11)
• Quill-type (Figure 12)
Adjusting the handlebar height on a direct-connect stem
affects the headset bearing adjustment. This procedure
requires special tools and training so this should only be done
by your dealer.
To align a direct-connect stem
1. Loosen 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).

Never ride your bicycle with a quill stem raised above the
minimum insertion mark. A quill stem that is positioned too high
can damage the bike and can cause you to lose control and fall.
Make sure the minimum insertion mark.
To align or adjust a quill-type stem
To adjust the height of the adjustable-rise stem in Figure 12,
first change the stem angle, which gives access to the stem
expander bolt.
1. Loosen the stem expander bolt two to three turns.
2. Tap the top of the stem expander bolt with a wood or
plastic-faced mallet to loosen the stem wedge.
3. Adjust the handlebar to the desired height, but with the
minimum insertion line inside the frame (Figure 13). A
minimum of 23/4” (70 mm) of the stem quill must always
remain in the frame.
4. Tighten to 120 lb•in (13.6 N•m).
To change the angle of an adjustable-
rise stem
1. Loosen the angle adjustment bolt (Figure 12) until the stem
angle can be changed.
2. Position the stem to the desired angle.
3. Tighten the angle adjusting bolt to 150-170 lb•in (17-20.3
N•m).
Saddle
The correct adjustment of the seat angle is largely a matter of personal preference.
With proper adjustment, the right bike seat will be reasonably
comfortable even for long rides.
To select the saddle angle, first try riding with the top of the
seat parallel to the ground. For bikes with rear suspension, try
tilting the seat nose down slightly so that compression of the
rear shock under your body weight (sag) results in a level seat.
The seat may also be moved forward or backward along the
seatpost to increase comfort as well as adjust the distance to
the handlebar.
Never engage the seatpost binder with the seatpost out of the
frame.
To adjust the angle of the seat
1. Loosen the seat fixing bolt (Figure 16) just far enough so the

Extended riding with a poorly adjusted
saddle or one that does not properly
support your pelvic area can cause
injury to your nerves and blood vessels.
If your saddle causes pain or numbness,
re-adjust the saddle position. If after
adjustment your saddle still causes pain
or numbness, consult your dealer about
further positioning or replacing the
saddle with one that better fits

ou.
A seatpost that is positioned too high can damage the bike and
can cause you to lose control and fall. Make sure the minimum
insertion mark (Figure 19) is inside the frame
seat can be tilted fore and aft.
Some seatposts use two bolts, where angle
adjustment is done by loosening one bolt and
tightening the other bolt.
2. Place a straight edge, such as a bubble level
or ruler, across the top of the seat to better see
the angle.
3. Adjust the seat and re-tighten the seat fixing
bolt according to the type of seatpost:
• Double bolts using a 5 mm allen wrench- 80-
125 lb•in (9.6-14.1 N•m).
• Single bolt using a 13 or 14 mm open-end wrench- 180-220 lb•in (20.3-24.9 N•m).
• Single bolt using a 6 mm allen wrench- 150-250 lb•in (17-28.3 N•m).
• Double bolts using a 4 mm allen wrench- 45-60 lb•in (5-6.8 N•m).
To adjust the seat height of a bicycle
1. Sit on the seat in riding position without shoes, while
someone holds the bicycle up.
2. Position the crank arms so they are parallel to the seat
tube.
3. Loosen the seatpost binder bolt, or quick-release.
4. Extend the seatpost until, with your heel resting on the
bottom pedal, your extended leg is straight (Figure 18).
When wearing your shoes there should be a slight bend in
your knee in a proper riding position; with the ball of your
foot on the pedal.
5. Make sure the minimum insertion mark on the seatpost
(Figure 19) is not visible above the bike frame. A minimum of
21/2” (64 mm) of seatpost must remain in the frame.
6. Close the seatpost quick-release, or tighten the bolt to 85-
125 lb•in (9.6-14.1 N•m)
To adjust the seat position of a tricycle
1. Loosen and remove the clamp bolts (Figure 20).
2. Move the seat mast to the desired position.
3. Install and tighten the seat mast clamp bolts to 85-125
lb•in (9.6-14.1 N•m).
