Can I replace my Mavic Cross One freehub body with a non-Mavic one? I want to switch to Shimano microspline.
There are two parts to this question.
- Generally, you cannot swap freehub bodies between manufacturers. There are some exceptions to this (some hub manufacturers use DT Swiss hub mechanisms, so there probably is compatibility there). Looking at Mavic's freehub body and Shimano's, they have very different shapes where they meet the hub shell, so I would expect them to be incompatible. The freehub body is a part of the freewheeling mechanism, and there are two popular designs for these (pawls and sawtooth ring gears), with numerous variations on each design. The body needs to fit its exact design.
- Usually, a single manufacturer will offer the same hub shell with different freehub bodies (microspline, Campagnolo, etc), and you can swap freehub bodies as long as you stay with the same manufacturer. This may not always be true, especially if the manufacturer has changed the freewheeling mechanism in their hubs since you bought your hub and they have no more old stock.
If your wheel has a ITS4 based hub body you can’t get a Mavic microspline freehub to replace it.
I’ve seen some 3rd party ITS4 microspline hub bodies pop up on AliExpress. YMMV
If you have the newer ID360 based hubs then Mavic does have a microspline hub body.
Seems the CrossOne uses the earlier FTS-X type bodies.
Pretty much zero chance of finding a microspline body for that.
And yes, as others have mentioned manufacturers mostly use proprietary interfaces for their freehub bodies and generally can’t be mixed and matched.
