Readjusting The Tension On Canyon Urban Bikes With Eccentric Bearing - Canyon Urban Manual

READJUSTING THE TENSION ON CANYON URBAN
BIKES WITH ECCENTRIC BEARING
On Canyon Urban bikes with multi-speed hubs the
tension of the Gates belt may slacken a little during
use.
You should therefore check the tension at regular
intervals and retighten the belt, if necessary. In the
case of a new Canyon Urban bike check the tension
more often and later on every 500 to 1,000 kilometres
(310 to 620 miles) of use. This simple maintenance
work is important, as too slack a belt can come off.
In addition, the belt wears down faster and is less
efficient.
Checking the tension
Check the correct belt tension at different points
either by using the special workshop tools of a bicy-
cle dealer or with the help of a special Gates Carbon
Drive app and your smart phone. Turn the crank in
half turns in between.
If the belt is not properly tensioned, you should re-
tension the belt.
Readjusting the tension
To readjust the tension move the eccentric bearing
together with the bottom bracket in the bottom area
of the BB shell.
Release the two bolts at the bottom side of the BB
shell by one to two turns by using an Allen key. Do
not unscrew the bolts entirely, but only so far until the
eccentric bearing can be moved easily.
To increase the tension put an Allen key of appropri-
ate size into the lateral tool mount.
Eccentric bearing

Turning the eccentric bearing, increasing tension
The easiest and safest way to do the work
i
is by hanging your Canyon Urban bike in a
workstand.
By moving the Allen key in direction of the front wheel
or to the rear, the crank set shifts to the front due to
the turning movement of the eccentric bearing, here-
by tensioning or releasing the belt. This requires in
general only little force.
As soon as the belt is tensioned, hold the eccentric
bearing with the Allen key in this position. Fix the
eccentric bearing by retightening the bolts on the
bottom side of the BB shell to the required, imprinted
torque value by using the Canyon torque wrench.
Check
After having the tension of the Gates belt properly
adjusted, check the correct fit of the eccentric bear-
ing in the BB shell. The eccentric bearing should not
stand out.
In case the eccentric bearing stands out, release it
once again and shift the eccentric bearing in axial di-
rection until it is flush with the BB shell on both sides.
Finish by tightening the bolt to the indicated torque
value. Do not exceed the indicated torque value!
Check the tension of the belt once again.

An overtensioned belt can increase the

wear of the gear hub as well as of the bot-
tom bracket and result in damage.
