The TrueKinetix freehub body is similar to the Shimano HG freehub. Therefor it fits with all Shimano / SRAM 8-12 speed cassettes.
Important! For 8-, 9- & 10 speed cassettes a 1.8mm spacer ring is required.
Campagnolo cassettes which are compatible with Shimano HG freehubs can be used on the TrueTrainer as well.
At the moment there are no freehub bodies available which are compatible with Campagnolo, Shimano micro spline, SRAM XD and XD-R bodies.
