Abstract
A device is disclosed for symmetrically and asymmetrically adjusting the effective length of pedal crank arms in bicycles. A separate setting member (1) is mounted instead of the conventional pedal axle between the commercially available pedal crank arm and the commercially available pedal. The setting member (1) consists of an eccentric (3) with a part (4) that forms the pedal axle and of a counter-piece (5) with a screw part (6) that corresponds to the eccentric (3). The counter-piece (5) and the eccentric (3) are both provided with driving elements or driving recesses. When the device is mounted, the driving elements engage associated driving recesses and define the effective length of the pedal crank arm. In order to associate the driving recesses to the driving elements, and thus to adjust the effective length of the pedal crank arms, the pedal crank is rotated backwards at the same time as a free-wheel device is actuated.
