This is a 16 x 3.5 Campy that was stripped, cleaned, and primed several year ago. It is undamaged. The hub is 78mm wide, and rotor is a 70mm hole and 90mm bolt pattern --- maybe for an early Honda. However, this is the same pattern that is used on Ducatis with the bolt-on rotor rotor adapters [that I do not have]. Want $250 plus shipping; again, what I paid several years ago. MikeV
