    Upgrade size of BB7 rotor from 160 to 180??

    Hi all,

    I'm building up a new bike and I have a new set of BB7 brakes sitting around and I would like to install them on my new bike. They are front and rear 160.
    I have an extra new 180 G2 rotor as well, and I'd like to put that on the front ( swap out the 160 for the 180). I don't think I can just stick the 180 on there and have it fit properly. What do I need to buy? Link to what I need, if anything.

    Thanks for any answers.

    Adapter for the brake caliper that will put it at the right location for larger rotor. Adapter itself depends on what mount you have in your fork (PM or IS).

    You guys rock, thanks for quick responses. I'll see if the local shop has any around and if not just order one.

    fyi i just switched to 180 from 160 front and got a whole kit for only $54, that's rotor, caliper w/new pads, adapter, bolts from Jensonusa

    definitely a great upgrade
