WTB avid bb-7

[Boumm]

I'm looking for an avid bb-7 for front, well is there a difference between the front and rear ones?

Thanks

You might also want to add what size rotor you are looking for.

The difference is in the mounting adapter for the caliper. Avid sells their CPS adapters for about $8 - 15 a piece. You can then change your caliper to line up with a 160, 180, or 203mm rotor, front or rear. The thing is that a 160mm adapter for the front is not the same as one for the rear.

I have about four of the 160mm front adapters sitting in my brake parts box. I once bought a rear brake and swapped out the adapter because the shop had rear brakes only on clearance.
