    Avid Elixir 9 Trail & Shimano M615's??

    650b bike has Shimano M615's w/ 180 Shimano rotors...

    29er has Avid Elixir 9 Trails w/ 180mm rotors also (brand = unsure)...

    Can I successfully swap brakes over from one bike to the other? (keeping rotors where they are)

    T.I.A

    Maybe. Shimano rotors can have quite a narrow brake track so you need to watch the fit. If the pads overhang the arms on the inside of the track it'll be ok. Overlap at the outside is...bad.

    Shimano brakes usually fit on other brand rotors just fine.

    maybe is right. assuming the OD of the rotors is the same, and there is no difference in offset. I'm assuming there is none if talking about two six bolt rotors, they may follow a slightly diff plane if swapping between centerlock-6bolt from one bike to the other. totally guessing, i have no idea and no way to measure.

    assuming there are no such interference problems, i would say that the narrower shimano pads might work on the wider avid rotors, but you may have a wear issue using the wider avid pads on the relatively narrow shimano rotor.

    10x have gone ahead and swapped them over (front initially to see if it works)...

    All seems ok at the mo... little adjustments needed before tightening down.

    Spanner called in for a little rotor straightening.

    Avids are a little snug on the Shimano rotors. Which is weird as all rotors are roughly 2mm in width!?

    Can always change em back if they don't play nice ;-)

    Shimano brakes have more pad clearance and maybe the Avids are starting to seize up. They do that.

    There are slight differences in the thickness of rotors. Shimano rotors are 1.8mm thick but some others are 1.75 etc. I use Formula rotors on my bike with bigger rotors because they are thicker. They are noticeably stiffer and less likely to get bent.
