Abstract
The present disclosure describes a gearshift mechanism for adjusting a gear ratio between a traction means, such as a chain, and a multi-sprocket gear set which can be rotated around an axle. The gearshift mechanism is configured to move the traction means in relation to the sprockets, such that an adjustment element is moved into the rolling motion of the traction means, thereby causing movement off of one sprocket and movement onto another sprocket.
