The PRO ACTIV back-pedal brake can be
used for chain gears or hub drives with a

automatic wear compensation for the brake
pads.

the physical limitations of the driver, the
springs of the system are available in three
strengths. These can also be replaced
retrospectively. Contact your dealer
immediately who will arrange the replacement
of the springs by PRO ACTIV.
The back-pedal brake is delivered with a crank
release function which allows reverse driving
