Front Derailleur Clamp

I call upon you all again for some more tech wisdom!

Trying to fit a new Campy front derailleur onto an old steel frame. The clamp's too big.

I don't have a Micrometer to measure the tube width but I know its a reynolds frame. (and the seat post is 26.2mm.)

The question - Can I get a clamp that small (ball park 28mm)? I was trying to avoid using a shim.

Many thanks in anticipation.

Rich

    but in answer to your question Yes.

    28.6mm

    Cheers Nick,

    Definitely a 28.6mm tube, (Just measured using link-thanks).

    Trouble is I can't find a clamp of that size to fit the Veloce FD.

    are you wanting a mech or a band?

    for adapters.

    Sorry I haven't been clear. I've got the Mech with clamp but the clamp is 31.8mm and I need 28.6. After a new clamp.

    make up some shims then?

    are Campy clamps changeable?

    I didn't think that any of the contemporary Campag front mechs come with clamps - they are all braze-on flavour and separate clamps are available. Only I do not think they do a clamp in 28.6.

    I am guessing your Veloce FD is from an older product line. You might be able to get the exact same with a 28.6 clamp.

    Be wary when running Campag gears of different ages with Ergopower shifters of differing age. If you see what I mean.

    Thanks, I haven't found one in 28.6 and think I may have to (reluctantly) result to the shim solution.
