  1. Does anyone make an adapter to use a FD with a 31.8 mm clamp size on a frame that takes a 28.6 mm?
    If not, any suggestions on how to make it work? Thanks in advance.

  2. I had this issue when moving front d from a ti frame to a steel frame. My REI sold me a simple grey
    plastic shim that worked perfectly. It not only did the shimming, it also protected the frame from
    smulching by the derailleur clamp.

  3. I don't know of any such adapter, but I think you could make up some metal shims to put under the
    31.8 FD to fit it onto the smaller seat tube size. Try cutting up a Coke can.

    I used those extra rubber things you get with a cat-eye computer fitting


    kit. You know the ones to accommodate different size forks and handlebars when you fit a computer !

    If it were me, I'd just cut a 1/2" piece of Schedule 40 PVC pipe and make my own shim.

    The best solution is really to get a new deraileur that is 28.6. Front deraileurs are not that
    expensive (except you know who). I can even sell you my new DA FD-7700, 28.6 clamp for $45 shipped.
    If yours is also DA 7700, we can trade.
