HEADSET
THREADLESS HEADSET: AHEADSET
®
The special feature of this system is that the stem
is not encased by, but rather clamped onto the fork
tube, which in this case is threadless. The stem is an
important part of the headset bearings. Its clamping
force secures the bearing in its set position.
Release the clamping bolts located on the sides or
rear side of the stem.
Gently tighten a little the countersunk adjusting
bolt on the top by using an Allen key.
Realign the stem with the frame so that the handle-
bars are not slanted when the wheel points straight
ahead.
Retighten the clamping bolts located on the side
of the stem by using an Allen key. Use a torque
wrench and never exceed the maximum tightening
torque! You will find the prescribed values in chap-
ter "Recommended tightening torques", directly on
the components and/or in the manuals of the com-
ponent manufacturers.
Check the headset for play, as described further
below. Be sure not to adjust the bearing too tight.
To do the check stand in front of your Canyon and
take the front wheel between your knees. Take hold
of the handlebars at the brake levers and try to turn
them relative to the front wheel. If you are able to turn
the handlebars, retighten a little the clamping bolt(s)
of the stem.
Check the secure seat of the stem after
you have adjusted the bearing! A loose
stem may throw you off your bike!
Adjust the bearing play by means of the countersunk adjusting bolt
at the top after releasing the clamping bolts on the side
Retighten the clamping bolts located on the side of the stem by using
an Allen key
Try twisting the handlebars relative to the front wheel
Do not tighten this bolt, as it is intended for
!
adjusting the play!
Bear in mind that by overtightening the
bolts the stem can crush the steerer tube.
I-LOCK HEADSET
The special feature of this system is that the stem
is clamped onto the fork tube, which in this case is
threadless. The stem is an important part of the head-
set bearings. Its clamping force secures the bearing
in its set position. Unlike the widely spread Ahead-
set
®
system, this system allows a bearing adjustment
with a firmly clamped stem.
Check the clamping bolts on the side and in the rear
of the stem with a torque wrench according to the
torque marked on them. Never exceed the given
maximum torque.
Use a 2 mm Allen key and tighten the headless
screw at the head cup carefully clockwise by a
quarter turn to begin with.
Check the headset for play, as above described. Be
sure not to tighten the bearing too much.
If necessary, tighten the screw by another quarter
rotation and check again.
Make a final check by standing in front of your Canyon
and taking the front wheel between your knees.
