GEARS
CHECK AND READJUSTMENT
If this is not the case, you have to adjust the posi-
tion by means of the limit screw. The limit screws on
rear derailleurs are often marked "H" for high gear
and "L" for low gear. In this case high gear stands
for high transmission ratio, i.e. with the chain run-
ning on the smallest sprocket.
If the screws are not marked, you will have to find
out by trial and error. Turn one of the screws count-
ing the number of turns and watch the rear derail-
leur. If it does not move, turn the screw back to its
original position.
Turn the screw clockwise to shift the rear derailleur
towards the wheel and anticlockwise to shift it away
from the wheel.
Change gears to the biggest sprocket. Be careful as
you do so, as not to let the rear derailleur collide
with the spokes. When the chain runs on the big-
gest sprocket, see whether you can take the rear
derailleur even further by moving the shift lever to
the end of its travel. Then press the rear derailleur
further towards the spokes by hand. Spin the wheel.
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.
Be sure to go on a test ride in a place free
!
of traffic, after adjusting the gears of your
bicycle.
Reduce the swivel range of the rear derailleur with the limit screws
Check whether the rear derailleur remains clear of the spokes
To adjust the clearance between pulley cage and sprocket, turn the
bolt located at the front side of the drop-out
Improperly adjusted limit stops or a bent
rear derailleur mount can result in a severe
damage to the bicycle and a rear wheel blocking.
Risk of an accident!
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.

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 chainwheel, 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 gear cable by turning the
adjusting bolt through which it passes at the entry
to the shift lever. 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
+44 (0) 20 8501 2582.

Adjusting 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 the
!
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
improper 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!
