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!

SHIMANO Di2

The Di2 is the electronic version of the high quality
shifting groupsets from Shimano. Instead of cables
the signal is transmitted by wires. The rear and the
front derailleurs are moved by small electrical mo-
tors. With an oblique running chain the Di2 front
derailleur is even readjusted automatically to avoid
grinding noises and unnecessary wear.
The power supply is provided by a rechargeable bat-
tery that is mounted to the frame.
CONTROL
With the Di2 you no longer have to move inwards the
entire brake lever or the lever of the conventional
Dual Control shift lever from Shimano, but only to
gently push control buttons. Shifting with the oblong
control button on the side of the brake lever shifts to
the larger chainrings/sprockets. Pushing the trian-
gular control button that is located behind the brake
lever makes the chain move to the smaller chainrings/
sprockets.
There is the option to have the control button func-
tion changed by your bicycle dealer if desired. The
only thing necessary to do so is a special test device
from Shimano that is also used for troubleshooting.
