Adjusting the brakes

Your bicycle’s brakes have been correctly adjusted in the factory or by your dealer. The
gap between the brake block and the wheel rim is approx. 1 – 1.5 mm. However, the
brake blocks are subject to wear, so that the gap becomes ever larger and the brake
lever travel becomes longer. The brakes must therefore be checked at regular intervals
and adjusted if the lever travel is too great or the brakes do not brake correctly.

Checking the brakes:

Pull the brake lever for the front or rear brake three quarters of the way back 
whilst pushing the bicycle.

The rear wheel should lock, or

the front wheel should brake so strongly, that the bicycle begins to tip over 
towards the front.

Adjusting the gap between the brake pad and the wheel rim

Turn the cable adjustment screw (adjusting bush). To increase the brake pad gap, the
adjusting screw is turned towards the inside (clockwise). To decrease the brake pad
gap, the adjusting screw is turned towards the outside (anticlockwise). The gap bet-
ween the brake block and the wheel rim should be 1 mm.

If necessary, adjust the spring 
tension using the spring 
adjustment screw so that both 
brake arms move symmetrically.

Subsequently, check that the 
brakes work correctly 
(see page 26).

Brake levers

Standard brake levers

The bicycle is fitted as standard with a suitable brake lever.
Check regularly that the brake lever does not contact the handlebar grip when you pull
it. Push the bicycle backwards and forwards to determine whether or not there is still
sufficient braking power. If the bicycle rolls slightly, you must adjust the brake lever or
have the brake blocks replaced.

Wheel rim brakes

V-brakes are very powerful lever brakes. Acquaint yourself with the V-brake 

and use the braking power sparingly. Practise emergency braking until you are 
in full control of the bicycle even when braking very strongly.

The improper use of additional sprung elements (power-modulators) can lead to 
serious falls. The spring power of the power modulator is dependant on the actual
total weight of the bicycle.

If the brake blocks are worn to the extent that the notches are no longer visible, 
have them replaced by a specialist workshop.
