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. An element has threads to threadably engage the axle shaft at the first end. Each of the enlarged end and the element are configured with surfaces so as to be fixably secured to couplers of a bicycle trainer.

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.

Abstract: The application discloses a roller assembly that utilizes internal resistance components to increase resistance to enhance training intensity. The internal resistance components include a rotatable resistance component or impeller coupled to an outer tubular body of the roller. Embodiments disclosed also include a second resistance component to restrict rotation of the rotatable resistance component increasing the torque required to rotate the outer tubular body. In an illustrative embodiment, the rotatable resistance component forms an impeller which is disposed in a fluid chamber within the tubular body and the second resistance component is disposed in the fluid chamber and maintained in a stationary position to impart resistance to rotation, thus increasing the torque required to rotate the outer tubular body.
