• Anyone able to help with question about BB5/BB7s?

    I've got a couple of bikes set up with BB7s and Shimano rotors - I recently read somewhere BB5/BB7 need a deeper rotor than what Shimanos come with, and to only use them with Avid rotors.

    Is there any truth to this statement? If so, is there anywhere I could get a correctly sized centerlock rotors so I don't have to shell out for adapters as well as rotors (the Avid G2/G3 only come in 6 bolt)?

    Avid's website is particularly not helpful.
