  1. Hi

    I have a Fort frame with a front-changer braze-on, which obviously
    limits the minimum diameter of the larger chainring. I have a Campagnolo
    Xenon triple changer, do you think it would cope with a 48-38-28 tooth
    chainset?
    TIA

    Depends on how high up the braze-on bracket is but I would expect it to be
    OK, even if you can't quite lower the mech to the ideal height.

    I found a Campag triple worked reasonably well when I tried a 50t in place
    of a 52 without lowering the mech at all (other rings were 39-26). My
    braze-on mech couldn't be raised high enough for a 53 though.

    I guess you're thinking of using some other chainset but note that the
    minimum size for Campag middle ring is 39t.
