Bicycle chain
Use a pin spanner to turn the eccentric until
the correct chain tension is achieved.
Finally, tighten the screws on the side of the
bottom bracket back with the correct torque.
You can find the correct torque for this in the
chapter 33.3 “Torques for screwed connec-
tions”.
While doing this, hold the eccentric tight
with a pin spanner, so that the eccentric does
not move while tightening the screw.
In this operating manual, the servicing and
handling of the typical and commonly sold
brake components as featured in modern pe-
delecs are described. Your bicycle is supplied
with the correct operating manual for your
specific brake system. If you have any ques-
tions about the assembly, setup, servicing and
operation of this part of your bike, please con-
tact a pedelec specialist retailer.
Brake pads and brake shoes are subject to
wear due to their constant use. You have to
check the level of wear at regular intervals.
Grooves on the brake shoes serve as markings
to help you to identify the level of wear. If these
are no longer visible, the brake shoes have to
be replaced. Always replace both brake shoes
at the same time.
23.1 Important information and
precautionary measures
Check the chain again for the correct tension.
2-3 cm
Only loosen this screw with two
or three turns anti-clockwise -
do not completely unscrew it!
The correct chain tension is
achieved in two areas. Firstly,
the bottom bracket is located
over the central line of the eccentric
and below the central line of the eccen-
tric. The first approach is better if the
seat cannot be set low enough or if ad-
ditional ground clearance is required.
Otherwise, the second approach is more
recommended.
23. Brakes, brake levers
and braking systems
Maintenance work on the
brakes has to be undertaken by
a specialist.
No oil-based liquids should ever be
applied to brake pads, rim brake sur-
faces, brake shoes or brake discs. This
reduces the effectiveness of the brakes.
