If your freehub is worn out or if you want to change your system, you should think about replacing the freehub. In this video I’ll show you how to do it.

Ratchet systems require less maintenance and are more fail-safe than pawl systems. If you don’t want to replace the whole hub directly, then my advice is to upgrade.
