C. Handlebar height and angle
Your bike is equipped either with a “threadless” stem, which clamps on to the outside of the steerer tube, 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, your dealer may be able to change handlebar height by moving height
adjustment spacers from below the stem to above the stem, or vice versa. Otherwise, you’ll have to get a
stem of different length or rise. Consult your dealer. Do not attempt to do this yourself, as it requires special
knowledge.
If your bike has a “quill” stem, you can ask your dealer to adjust the handlebar height a bit by adjusting stem
height.
A quill stem has an etched or stamped mark on its shaft which designates the stem’s “Minimum Insertion” or
“Maximum extension”. This mark must not be visible above the headset.
!
WARNING: On some bicycles, changing the stem or stem height can affect the tension of the
front brake cable, locking the front brake or creating excess cable slack which can make the front
brake inoperable. If the front brake pads move in towards the wheel rim or out away from the wheel
rim when the stem or stem height is changed, the brakes must be correctly adjusted before you
ride the bicycle.
!
WARNING: The 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.
!
Your dealer can also change the angle of the handlebar or bar end extensions.
!
WARNING: An insufficiently tightened stem binder bolt, handlebar binder bolt or bar end
extension clamping bolt may compromise steering action, which could cause you to lose control
and fall. Place the front 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 front wheel, turn the handlebars
in relation to the stem, or turn the bar end extensions in relation to the handlebar, the bolts are
insufficiently tightened.
D. Control position adjustments
The angle of the brake and shift control levers and their position on the handlebars can be changed.
Ask your dealer to make the adjustments for you.
E. Brake reach
Many bikes have brake levers which can be adjusted for reach. If you have small hands or find it difficult to
squeeze the brake levers, your dealer can either adjust the reach or fit shorter reach brake levers.
!
WARNING: The shorter the brake lever reach, the more critical it is to have correctly adjusted
brakes, so that full braking power can be applied within available brake lever travel. Brake lever
travel insufficient to apply full braking power can result in loss of control, which may result in
serious injury or death.
