    If I want to run a 180mm front rotor on my front IS fork, what rear adapter is the equivalent, or is there one?

    CompCy has 2013 mounts for a dollah more than 2011 mounts...but rear only.

    actually, some will. for instance, i think a front 180 works as a rear 160 with avids. there really is no exact science, but i've mixed and matched some stuff without catastrophic failure. i would only recommend this in a pinch to get a build rolling.

    in this case, just buy the correct adapter dude

    I bought the right adapter, just wanted to save on shipping.

    FWIW, I'm fairly certain the the rear IS mount is a front disk mount -20mm. So, a 203 front is a 180 rear, or something like that. I'm just not sure whether it's -20 or +20 or +/- 10...

    Is not the width of the adapters vastly different??

    I don't think so, at least it doesn't appear as such. I'll try and check when I get home.

    A 160 front is a 140 rear, 180 front 160 rear.
