Bicycle Owner’s Manual 13
C. Handlebar height and angle
Your bike is equipped either with a “threadless” stem,
which clamps on to the outside of the fork sha, or with a
“quill” stem, which clamps inside the steerer tube by way
of an expanding binder bolt. If you aren’t absolutely sure
which type of stem your bike has, ask your dealer.
If your bike has a “threadless” stem (g. 6) your dealer
may be able to change handlebar height by moving
height adjustment spacers om below the stem to above
the stem, or vice versa. Otherwise, you’ll have to get a
stem of dierent length or rise. Consult your dealer. Do
not attempt to do this yourself, as it requires special
knowledge.
If your bike has a “quill amped mark on its sha which
designates the stem’s “Minimum Insertion” or “Maximum
Extension”. This mark must not be visible above the
headset.
WARNING: A quill stem’s Minimum Insertion Mark
must not be visible above the top of the headset. If
the stem is extended beyond the Minimum Insertion
Mark the stem may break or damage the fork’s steerer
tube, which could cause you to lose control and fall.
WARNING: On some bicycles, changing the stem or
stem height can aect the tension of the ont brake
cable, locking the ont brake or creating excess
cable slack which can make the brakes and the shiers
inoperable. If the brake pads move in towards the wheel
rim or out away om the wheel rim when the stem or stem
height is changed, the brakes must be correctly adjusted
before you ride the bicycle.
Some bicycles are equipped with an adjustable angle
stem. If your bicycle has an adjustable angle stem, ask
your dealer to show you how to adjust it. Do not attempt
to make the adjustment yourself, as changing stem angle
may also require adjustments to the bicycle’s controls.
WARNING: Always tighten fasteners to the correct
torque. Bolts that are too tight can stretch and
deform. Bolts that are too loose can move and
fatigue. Either mistake can lead to a sudden failure of the
bolt, causing you to lose control and fall.
Your dealer can also change the angle of the handlebar
or bar end extensions.
WARNING: An insuciently tightened stem clamp
bolt, handlebar clamp bolt or bar end extension
clamping bolt may compromise steering action,
which could cause you to lose control and fall. Place the
ont wheel of the bicycle between your legs and attempt
to twist the handlebar/stem assembly. If you can twist the
stem in relation to the ont wheel, turn the handlebars in
relation to the stem, or turn the bar end extensions in
relation to the handlebar, the bolts are insuciently
tightened.
WARNING: Be aware that adding aerodynamic
extensions to handlebars will change the steering
and braking response of the bicycle.
D. Control position adjustments
The angle of the brake and shi control levers and their
position on the handlebars can be changed. Ask your
dealer to make the adjustments for you. If you choose to
make your own control lever angle adjustment, be sure to
re-tighten the clamp fasteners to the recommended torque
(Appendix D or the manufacturer’s instructions).
E. Brake reach
Many bikes have brake levers which can be adjusted
for reach. If you have small hands or nd it dicult to
squeeze the brake levers, your dealer can either adjust
the reach or t shorter reach brake levers.
WARNING: The shorter the brake lever reach, the
more critical it is to have correctly adjusted brakes,
so that ll braking power can be applied within
available brake lever travel. Make shure, that the brake
levers never touches the handlebar or the grips, no matter
how hard you pull them. Brake lever travel insucient to
apply ll braking power can result in loss of control,
which may result in serious injury or death.
4. Tech
It’s important to your safety, performance and
enjoyment to understand how things work on your
bicycle. We urge you to ask your dealer how to do the
things described in this section before you attempt them
yourself, and that you have your dealer check your work
before you ride the bike. If you have even the slightest
doubt as to whether you understand something in this
section of the Manual, talk to your dealer. See also
Appendix A, B, C and D.
A. Wheels
Bicycle wheels are designed to be removable for easier
transportation and for repair of a tire puncture. In most
cases, the wheel axles are inserted into slots, called
“dropouts” in the fork and ame, but some mountain
and road bikes use what is called a “through axle” wheel
mounting system.
