connected with the tightening device which is movable between an engagement position and a release position and in the engagement position form-fittingly retains at least one coupling piece of the axle and in the release position releases the coupling piece. ### Claim 12 (depends on 10) The axle system according to claim 10 wherein the tightening device comprises a tightening bush with an external thread at which the coupling device is received wherein rotary movement of the tightening bush can cause axial displacement of the tightening bush and thus of the coupling device. ### Claim 13 (depends on 12) The axle system according to claim 12 wherein the tightening bush is connected with an operating lever for tightening and releasing. ### Claim 14 (depends on 10) The axle system according to claim 10 wherein the coupling device form-fittingly encircles the coupling piece in the engagement position. ### Claim 15 (depends on 10) The axle system according to claim 10 wherein the coupling device comprises at least one engagement component which in transfer from the engagement position to the release position is relocated radially outwardly. ### Claim 16 (depends on 10) The axle system according to claim 10 wherein the coupling device comprises a plurality of engagement components which in transfer from the engagement position to the release position are relocated radially outwardly. ### Claim 17 (depends on 15) The axle system according to claim 15 wherein the engagement components the coupling device are preloaded radially inwardly by means of a preloading device. ### Claim 18 (depends on 10) The axle system according to claim 10 wherein the coupling piece is fixedly though releasably connected with the axle. ### Claim 19 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
