Axle system for retaining e.g. front wheel of muscle-operated bicycle, has inner and outer clamping parts axially moved against each other by rotation, where outer diameter of inner part is greater than outer diameter of axle at end region

摘要

The system has a clamping mechanism with a tensioning arrangement (5) and a terminal (7) arranged at two end regions of an axle (3), respectively, where the mechanism fastens wheels at a bicycle component. The tensioning arrangement includes an inner clamping part (12) with an external thread (13) and an outer clamping part (14) with an internal thread (15), where the clamping parts are axially moved against each other by rotation. Outer diameter of the inner clamping part is greater than outer diameter of the axle at one of the end regions. An independent claim is also included for a bicycle component comprising an axle system.
