    trek 3900 disc w/ bb7

    After failing to get my extremely crappy tektro novela brakes to work for me, i have decided to get some respectable brakes so that i can feel safe and confident on the trails. My only concern is if bb7's are compatible with my rotor or if a new rotor can fit on my hub. Can anyone help me out? Thanks.

    Yes and yes (assuming you have a regular, 6 bolt rotor mount).

    A set will come with calipers and rotors.

    Will wtorek just fine. I had 3900 d and also upgraded to bb7 with sd7 levers. Makes a huge difference. Properly setup give a one finger stopping power
