1. An axle arrangement for a rear hub of a bicycle, comprising:
- an axle skewer having;
at a first end, threads formed on an outer surface thereof configured to extend through an aperture in a frame fork of the bicycle, andat a second end remote from the first end, an enlarged head having an annular surface facing the first end wherein the annular surface of the enlarged head is fixed to the axle skewer such that rotation of the enlarged head is prevented relative to the axle skewer; and
a fastener having threads to threadably engage the axle skewer at the first end, and wherein each of the enlarged head and the fastener are configured with surfaces so as to be fixably secured to couplers of a bicycle trainer, said surfaces comprising oppositely facing annular surfaces when the fastener is threaded upon the skewer; and
an adapter having an aperture configured to receive the first end and through which the axle skewer is slidable such that the adapter is slidable along the axle skewer from the first end, the adapter comprising a first annular surface configured to releasably engage the annular surface of the enlarged head and an annular conical surface extending in a direction opposite the first annular surface.

Abstract
An axle arrangement for a rear hub of a bicycle includes an axle skewer having at a first end threads formed on an outer surface thereof, and at a second end remote from the first end, an enlarged head having an annular surface facing the first end. A nut has threads to threadably engage the axle shaft at the first end. Each of the enlarged end and the nut are configured with surfaces so as to be fixably secured to couplers of a bicycle trainer. A kit includes the axle arrangement and two or more of a spacer and/or an adapter wherein each of said spacers and/or adapters are separately configured to adapt the axle arrangement to a different manufacturer of a bicycle.
