46 ADJUSTMENT TO THE RIDER HANDLEBAR HEIGHT
Release the bolt at the top of the fork steerer tube
which serves to adjust the initial bearing pressure
and remove the Ahead cap.
Release the stem clamping bolts on either side of
the stem and pull the stem off the fork.
Now you can remove the spacers.
Apply a litte Canyon carbon assembly paste in the
stem clamping area.
Remount the stem entirely on the fork steerer tube
and slip the spacers you have removed above the
stem.
Stems come in very different lengths and
shaft and binder tube diameters. A stem of
inappropriate dimensions can become a source of
danger: Handlebars and stem may break, causing
an accident in the process. When replacing any
parts be sure to only use parts that bear the ap-
propriate mark and, to be on the safe side, original
spare parts.
Make sure the handlebar clamping area
i
is free of sharp edges. If you intend to
make any changes, contact our service hotline at
+44 (0) 20 8501 2582.
Release the bolts on the side of the stem
Remove the spacers under the stem and place them above the stem
Readjust the bearing and retighten the stem
When removing the spacers you will have
i
to shorten the steerer tube. This change is
irreversible. For this reason, a shortening should
not be carried out until you are absolutely sure
about the seating position. Have this job carried
out by an experienced mechanic. We recommend
that you contact our Canyon workshop through
our service hotline at +44 (0) 20 8501 2582.
HANDLEBAR HEIGHT
If you want to turn around the stem, you have to addi-
tionally remove the handlebars.
To do so release the bolts of the stem front plate
clamping the handlebars and remove them careful-
ly.
Apply a little Canyon carbon assembly paste in this
clamping area and retighten the handlebars after
having turned around the stem.
Centre the handlebars accurately in the stem
clamp.
Retighten all bolts of the stem clamp with a torque
wrench by observing the correct tightening torques.
Please note that when using carbon assembly paste
you normally need not use the maximum tightening
torque. It will do already to tighten the bolts with
tightening torques that are 20 to 25 % below the
maximum tightening torques, i.e. 6 Nm instead of 8
Nm. That will prevent the material from damage.
Readjust the bearing.
Realign the stem by making sure it is in alignment
with the front wheel and at right angle relative to
the handlebars and the direction of motion. After
realignment of the stem retighten it and check
whether the handlebars resist twisting and turning
(see chapter "The headset").
Verify that the handlebar clamping area
i
is free of sharp edges. If you intend to
make any changes, contact our service hotline at
+44 (0) 20 8501 2582.
If you have a Canyon mountain bike with
a carbon steerer tube (which you can tell
by the black or black shining colour in the stem
slit), you have to be extremely careful when tight-
ening the stem. This is a job for experts only!
ADJUSTMENT TO THE RIDER
Release the bolts of the front plate of the stem
Retighten the bolts
Note that the bolted connections of stem
and handlebars have to be tightened to the
specified tightening torques. You will find the pre-
scribed values in chapter "Recommended tighten-
ing torques" or in the enclosed manuals of the
component manufacturers. Contact, if necessary,
our service hotline at +44 (0) 20 8501 2582. If
you disregard the prescribed values, the handle-
bars or stem may come loose or break. This can
lead to a severe crash.
