Hey, hope everyone had a good weekend? I have a question about using an 8 speed free-wheeel. I want to upgrade my 6speed Chorus with an 8 speed freewheel. I really like my wheel-set and would like to still use it. I have found a few 8speed Sachs freewheels on E-Bay, however am not sure as to the feasibility/durability of such a change. I understand that I will need to space the locknut on the drivetrain side of my rear hub, as well as re-dish. Is this a wise modification? Or should I just go with a 7speed freewheel?
