    BB7 Road and rotors bigger than 160mm

    If this has been asked before I apologize, I did a search and didn't turn up anything.

    I am thinking of putting together a monstercross bike with drop bars, and so am looking at the Avid bb7 road for my brakes. I am thinking of going 185mm rotors in front, but am unclear whether the BB7 road is able to be used for this application like the mountain version is. I understand that at a minimum I would need to acquire a separate disc and spacing adapter, but was unsure if there was any bigger incompatibility.

    thanks

    Your proposed setup will work fine. The BB7 road caliper has a shorter cable pull than the mountain version - that's really all that's different between the two.

    In fact, you could also use the mtn caliper with drop bars and aero levers if you set the pads really close to the rotor. The braking action feels a bit weird at first but you will quickly learn to adapt your technique.
