Ok so I'm going rear freehub, I need to get my freewheel off. I've removed the lockring and bearings and pawls, now I'm left with the black bit thats inside all of that. I don't have access to a grinder, I have a vice though. We've tried a tool bolted down with a ratchet thing on. We then used a 2ft pole on top of that. Maybe smashing the crank round would work? Joe
