For use with CycleOps Power Classic series trainers (Wind, Mag, Mag+, Magneto, and Fluid2).
Great news for 20 inch rear wheel recumbent owners! The 20/24 Wheel Adapter makes it possible to use any newer CycleOps trainer with 20" or 24" rear-wheeled bicycle. The resistance unit of the trainer is raised to accommodate the smaller tire and the folding legs are replaced with shorter versions to keep the height of the mounted bike lower.
In order to use the trainer with SRAM internal speed hubs, you must disconnect the chain indicator on the hub.
