When driving up a hill, it should be noted
that it is only possible to change using the 9- /
10-speed cassette under heavy loads on the
chain. Changing using the top three chain
wheels is no longer possible if there is heavy
tension on the chain. It is therefore important to
switch to a smaller chain wheel as a
precaution.
Try to avoid selecting cross gears, as the
efficiency and service life of the chain will fall
significantly (more information can be found in
chapter 33).
For more information, please see the
instructions provided by the gear manufacturer.
16.3.2 Hub gears
The hub drive can be changed while driving
and also when stationary. No crank movement
is needed to change or only a small reduction
in torque is needed while driving.
The Rohloff hub gears are operated by
turning the grip shift. The gear selected is
shown in the display on the control panel.

16.4 Brakes
Normally there is one disc and one rim brake
fitted to the product. Where possible, both
brakes should be operated simultaneously and
the braking requirement reduced by driving in a
way that anticipates the requirement to reduce
speed if necessary.

16.4.1 Rim and disc brakes
The brakes are operated using the brake lever.

Please make sure that the braking
surfaces on the rim, the brake disks and the
brake pads on the rim breaks do not come into
contact with oils or greases which could
otherwise impair the braking effect. If rims,
brake discs or brake pads do come into
contact with oils or greases, the brake pads
must be replaced and the brake disc and rim
must be professionally cleaned with brake
cleaner (e.g., Weicon surface cleaner).
You can find further information in the brake
manufacturer's instructions.
