    Do I need an adapter for a rear 160mm rotor and a bb7 caliper?

    I want to run a bb7 capliper and a 160 mm rotor...do I need an adapter to attach it (the caliper) to my frame?

    Thanks!

    If you have standard mounts, the hardware included with the BB7 should be enough

    so I can just bolt the caliper directly to the frame without the adapter, right?

    The BB7 is a 74mm post mount caliper. So unless your frame uses 74mm post mounts (not aware of any that do) you need to use an adapter. If you purchased your brakes with 160mm rotors, than the adapter that came with the BB7 for the rear brake is the correct one.

    I've got a 160 rear here. If you want to do the fork, I'll throw the adapter in the box when I ship it back. Let me know.
