GEARS
CHECKING AND READJUSTING
If the pulley cage touches the spokes or if the chain
begins to move beyond the largest sprocket, you
should reduce the swivel range. Turn the screw
marked "L", until you are absolutely sure the rear
derailleur does not collide with the spokes.
Check the position of the pulley cage towards the
sprocket. The gap between pulley and the largest
sprocket should leave a clearance of one to two
links at least.
The rear derailleur is equipped with a bolt located
at the drop-out front which serves the purpose of
adjusting this clearance. Screw in this bolt until the
clearance is as desired. Turn the cranks backwards
for checking purposes. The pulley should not touch
the sprocket during this movement, as well.
In case the clearance still does not suffice, chang-
ing gears being thus impeded, you have to short-
en the chain by one link. This means an increased
tension on the rear derailleur. It must, however, be
ensured that the chain can run on the largest chain-
ring as well as on the largest sprocket. Due to the
extremely oblique run of the chain, this gear should
however be avoided.
To adjust the clearance between pulley cage and sprocket, turn the
bolt located at the front side of the drop-out
Ask a helper to lift the rear wheel. By turn-
i
ing the cranks and shifting through you
can easily check the function.
Be sure to go on a test ride in a place free
of traffic, after adjusting the gears of your
bicycle.
FRONT DERAILLEUR
Adjusting the front derailleur requires a great deal of
experience. The range within which the front derail-
leur keeps the chain on the chainring without itself
touching the chain is very small.
It is often better to let the chain drag slightly on the
derailleur than to risk having the chain fall off the
chainring, which would interrupt the power train of
your Canyon.
As with the rear derailleur, the cable of the front
derailleur is subject to lengthening and hence to re-
duced precision in gear changing.
Increase the tension of the cable by turning the
adjusting bolt at the down tube of the frame. This
works mainly, as described in section „Checking
and readjusting the gears".
Reduce the swivel range of the front derailleur with
the limit screws.
The initial adjustment of the front and rear
!
derailleur is a job for an experienced me-
chanic. Maldadjustments may cause severe me-
chanical damage. For more information be sure
to read the operating instructions of the gear
manufacturer. In case you face any problem with
the gears, please contact our service hotline at

Adjusting the swivel range of the front derailleur
Adjusting the front derailleur is a delicate
job. Improper adjustment can cause the
chain to jump off, thus interrupting the power
train. Risk of an accident! Adjusting the front de-
railleur is a job for professionals.
After having adjusted the gears and chain
!
it is essential to take your Canyon for a
test ride in a level, unfrequented area (e.g. in a
parking lot)! If the adjustments turn out to be im-
proper when riding in road traffic, you may lose
control over your Canyon.
Always check after an accident whether
!
the guide plates of the front derailleur are
still parallel to the chainrings!
