Mavic Freewheel Bushing
This is a fairly common problem with Mavic wheels. The polymer bushing on the end of the freewheel wears out and causes a lot of play in the entire cassette. In this case it was spinning around while broken in 2 pieces, which made it worse. Right now there is no Canadian distributor for Mavic and we wanted a solution immediately with no shipping involved. I machined a new bushing out of some polymer I had and the customer had his wheel on time.
