8.1.1 Checking the quick release

Check the position and clamping force of the
quick release lever. The quick release lever
must be flush with the lower housing. You must
be able to see a slight impression on the palm
of your hand when you close the quick release
lever.

8.2 Adjusting the gear shift
If you cannot select the gears effortlessly, you will
need to adjust the setting for the shift cable
tension.
 Carefully pull the adjusting sleeve away from
the shifter housing, turning it as you do so.
 Check the gear shift function after each
adjustment.
Crash caused by unfastened quick
release
A faulty or incorrectly installed quick release may
become caught in the brake disc and block the
wheel. This will cause a crash.
 Install the front wheel quick release lever on
the opposite side to the brake disc.
Crash caused by faulty or incorrectly
installed quick release
The brake disc becomes very hot during
operation. Parts of the quick release may become
damaged as a result. The quick release comes
loose. This will cause a crash with injuries.
 The front wheel quick release lever and the
brake disc must be situated on opposite sides.
Crash caused by incorrectly set clamping
force
Excessively high clamping force will damage the
quick release and cause it to lose its function.
Insufficient clamping force will cause a
detrimental transmission of force. The
suspension fork or the frame may break. This will
cause a crash with injuries.
 Never fasten a quick release using a tool (e.g.
hammer or pliers).
Only use the clamping lever with the specified
set clamping force.
