C.4.2 Attaching a Threadless Stem
Important! Do not disassemble the headset or lose any parts.
Be sure the end of the fork is on the ground or being held with
your free hand, because once you loosen the top cap the fork
assembly may fall out of the frame.
❶ Turn the front fork to face forward (i.e. the fork dropout is in
the furthest forward position). Figure 3.4
❷ Using a 5 mm Allen wrench loosen the top cap bolt on the
steerer tube and remove the top cap and bolt. Important! Do
not remove the spacers.
❸ 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.
❹ While holding the fork assembly in place, use a 6 mm Allen
wrench and loosen the stem pinch bolts. Slide the handlebar
assembly onto the steerer tube.
❺ Place the top cap onto the top of the steerer tube. Insert and
tighten the top cap bolt until it is snug.
Do not over tighten.
❻ Using a 5 mm Allen wrench tighten the top cap bolt. Do the
following checks to determine if the headset is properly set.
Tighten or loosen the top cap bolt if necessary.
• Lift up the front wheel of the bicycle, if the wheel does not
move freely left to right the headset is too tight.

• Hold the handlebar, close the brakes and rock the fork back
and forth. If you hear a knock or clunking sound the headset
is too loose.
❼ Align and center the stem to the fork and wheel. Tighten the
stem pinch bolts until there is no play between the stem and
steerer tube. Note: There should be a 3 to 5 mm
(1/8"- 3/16")gap between the top of the stem and steerer
tube. Figure 3.5
