SHIMANO/SRAM Freehub

The standard body of a Tacx direct drive trainer is not compatible with all cassettes. Use this body to mount your SHIMANO/SRAM cassette. It’s easy to install, and all you’ll need is a 5 mm hex key.

The cassette body is compatible with 9-11 speed SHIMANO/SRAM cassettes. This version is used for trainers with Type 1 axles.
