    Such thing as a FD Clamp spacer?

    I have a Ultegra FD with a 34.9mm clamp. My bike, however is a 31.8mm seat tube. Is there any spacers available on the market that will remedy this? I was thinking about using some thick rubber stripping (its from a cyclocomputer mount) to wrap around the seat tube to give me that extra diameter. Does that sound smart?

    Thanks alot!

    -Jerry

    Yeah, my kid hauler has the same issue (though it's an MTB). I wrapped bike tube around the seat tube and clamped that. Flawless shifting for 8 months straight now.

    Braze ons and adapter clamps are the way to go, IMO. I hate not being able to move parts around bikes.

    I ended up with a new steel bike the year that Campy stopped making the smallest FD clamp in Record. Bought the next bigger one and clamped it with the rubber shim from a computer. Still working, 2000 miles later.

    That is very useful. It's getting harder to source 28.6 ders anymore. Thanks for the link

    Braze on is the way to go, but I disagree with the 28.6 being harder to get?

    FWIW, Nashbar has 28.6 braze-on clamp adapters for 2 or three bucks. I ordered a couple just to have around.

    You know it's going to be a good day when the stem and seatpost come right out.

    The Universal Cycles band clamp linked above is exactly what I need...except that I need to go from 31.9 to 28.6 and it looks like they don't carry that size. Anyone know where I could find one? thanks.

    I had the same problem with a Shimano FD. But I learned something interesting, most of their FDs use the same style clamp. So I unscrewed the bigger one and switched it with the clamp from an older FD. It worked perfectly.
