The rear hub on my Farley started slipping on my last ride. It may have been after trying to get up a steep rock section, and exerting a lot of force on the pedal. I pulled the freehub off, and everything looked pretty good to me. I didnt see any cracks in the hub shell, or the ring with the grooves in it where the pawls engage. Only thing i did notice was two strands of metal, about the size of a thick hair, that seemed to have been sheered off. I cant tell how that would have happened. Anybody have any ideas? I thought maybe the gear ring was spinning within the hub body, but i wasn't able to spin it by hand with little leverage.
