ATTACH THE HANDLEBAR
WARNING!
• Improper attachment of the handlebar may result in
damage to the stem post, steering tube and result in loss of
control, serious injury or death. Ensure the minimum
insertion marks on the stem post are not visible above the
top of the headset.
• Failure to properly tighten handlebar components may
result in loss of control, serious injury or death. Always
check the handlebar cannot move and is secured to the
frame before riding the bicycle.
There are four types of stems that attach the handlebar to the
steerer tube. It is either a quill, clamp (threadless), front load
and top load stems.
Attaching a Quill Stem
❶ Turn the front fork to face forward. Figure 3.3
❷ Position the handlebar assembly over the steerer tube.
Look at all the cables to be sure they run in a smooth arc
from the shifter or brake lever to the front brake or cable
stop on the frame. Important! If they are twisted or kinked,
the shifting and braking will not work.
❸ Insert the stem post into the steerer tube and adjust the
handlebar until the rider feels they have control of the
bicycle and are comfortable.

See Section 1, Fig. 1.2: Seat Height and Handlebar Reach
for guidelines. Important! Be sure the minimum insertion
marks do not go above the top of the headset and are
not visible.
❹ Using a 6 mm Allen wrench tighten the stem binder bolt at
the top of the stem post. Check the handlebar binder bolt(s)
to be sure they are properly tightened and the handlebar is
clamped in place. Note: See Section 4: Adjusting the
Handlebar if adjustments are needed.
