At least that's my understanding.
That thing wont come off 'till I unbolt it, clamp=chromoly,armature=cast Alu alloy,wheel=rubber\steel core\spinshaft, bolts\nutz=tempered steel. It's on a monoring mtb running 7spd rear. I torque super heavy.
Jumping onna big pointy rock would mess it! = why I cut me up a bashring.
Spins backward fine? Ummm, maybe a spring/ float design would be better for your bike types?
