I have fitted a Bionx kit to my Trek 6000. The anti spin on the axle bolt seems to be a long way out of the fairly shallow rear drop out. I have made sure nuts are very tight. I used a torque wrench last night but think it overdid it. I have now used the FT setting that has stood me in good stead for many years. Do I need some form of drop out adaptor and if so has anyone got a recommendation and or image stroke diagram of how an adaptor would work.
