Anyone have any experience with mangling the drive ring and freehub body on a rear Bulb? After about 6years use (which I am quite happy about), my freehub body is gouged from the drive ring, and a few of the teeth on the drive ring (in the hub shell if this is not clear) are broken off/mangled. Is it possible to replace the drive ring? It looks like it might be, but it would certainly be difficult to remove.
