    BB7 Caliper/Rotor size questions

    I have a set of BB7 with 160 mm rotors. I am thinking of picking up a 18 mm pair of rotors but want to make sure they will work with my calipers and frame. I have a 2011 Jabberwocky.

    1. Can either a 160mm or 180mm rotor be used with the same BB7 caliper? Or is there a speciifc caliper for each rotor size?

    2. Will most frames allow use of either 160 or 180 rotors by using the bb7 caliper mounts and the slotted caliper mount holes on the frame?

    1. Use the appropriate caliper bracket. The caliper is the same.

    2. See #1. The slotted mounts are not for different rotor sizes.

    The trouble with common sense is it is no longer common
