Axle system for a two-wheeled vehicle

A two-wheeler component, comprising:

• a first dropout and a second dropout and an axle system with an axle for receiving a wheel of a two-wheeled vehicle, including a clamping mechanism with at least one tightening device and at least one end device equipped to clampingly attach the axle received at the dropouts between the at least one tightening device and the at least one end device, the at least one tightening device receives a coupling device which is movable between an engagement position and a release position, wherein in the engagement position the coupling device form-fittingly retains a coupling piece of the axle, and wherein in the release position, the coupling device releases the coupling piece;
• and
• a decoupling device, said decoupling device is axially displaceable from a home position to a decoupling position and further to a release position, wherein the decoupling device is preloaded in the home position, wherein the tightening device comprises a tightening bush at which the coupling device is received, and wherein the tightening bush comprises an external thread engaging an internal thread of the dropout,
• configured to axially displace the coupling piece of the axle from the decoupling position to the release position and to activate a preloading device of an end device with which the axle with the coupling piece is automatically pulled out further of the tightening device, wherein the clamping mechanism is configured to clampingly attach a wheel between the tightening device and the end device to a two-wheeler component with a clamping force, the clamping force being independent of a possible rotary movement of the axle.
