    Use Avid BB7s with non-Avid rotor?

    Hey all,

    I want to put a drop handlebar on my MTB.

    Since it currently has Magura hydraulic brakes, I'd need to switch to mechanical calipers.

    The issue I'm facing right now is this: The bike is a Cannondale, and the hubs have FOUR bolts for the brake rotor. (Yeah, thanks for turning you back on a standard, Cannondale...).

    I would think that the mechanical Avid brake calipers would work with the Magura rotor (yeah, it's a special rotor made by Magura just for Cannondale).

    Anyone out there running Avid mechanical disc brakes with non-Avid rotors?

    Thanks for any insight!
    Despite the fact that I constantly recommend Kool-Stop brake pads-- no, I don't work for Kool-Stop. (Although their factory is just a few blocks from my house!)

    I ride drop bars off-road. (The excellent On-One "Midge.")

    I'm running BB7s on Shimano centerlock rotors. No problem. As long as they are 160mm you should be good to go.

    Yes, make sure they are the same rotor size.

    The other other problem you [i]might]/i] run into is the width of the brake path. For example, the brake path on Hope rotors is considerably smaller than Avid, so if you ran a Hope rotor, theres a possibility that the pads will where unevenly and bevel to a certain extent.

    Might as well give it a shot.

    I actually installed Juicy Three's (stock spec'd for 160) on a Cannondale that was equipped with the 4 bolt setup. The front rotor is 180 and the rear is 140. Ridiculous. Couldn't replace them so I had to experiment with a few different mounting brackets to get the calipers lined up properly, but with the right parts you will be able to set it up. I wish I could give you a part number for the brackets I used, but the ones I wound up using were not labeled so I don't even know myself. The rotors themselves are a hair wider, but did not pose a problem and the brakes set up perfectly.
