What is freehub driver?

Freehub/Drivers are what the cassette is attached to, and this is attached to the hub with bearings and some sort of ratchet or pawl system to allow the cassette to freewheel when coasting, and then engage when you start pedaling. Each one uses a unique spline interface to the cassette.

Are all freehub bodies the same?

Joyously, almost all of these cassettes share the same freehub body standard, whether they’re from SRAM, Shimano or any other brand. It’s possible to have this fitted to a mountain bike or gravel wheelset but the solution is a simple, thin spacer fitted to the freehub before the cassette is placed over.

Can you change freehub bodies?

You can either buy a new freehub body or if you’re lucky your local bike shop or bike recycling project may have a stash! Your replacement freehub body needs to have the same interface as your old one (meaning the same spline pattern) so it can fit onto your old hub.

What is the difference between ratchet and pawl?

The ratchet is usually a wheel with slanting teeth. The pawl is a lever tangential to the wheel with one end resting on the teeth. When the wheel rotates one way, the pawl slides over the teeth; when the wheel rotates the other way, the pawl catches in the teeth.

When should I replace my freehub?

There are no parts available, such as the pawls or springs. The small ball bearings are available as replacement parts. However, if the bearings are worn out and require replacing, it is very likely the entire freehub is needing replacement.
