    swapping derailleur clamps

    If I have a 34.9 Rival front derailleur, and a 31.8 dura ace, can I switch the clamps to make the dura ace 34.9 and the sram 31.8?

    Also, would this work if both derailleurs were shimano. For example, are the clamps the same for a 31.8 and 34.9 dura ace derailleur, aside from the diameter?

    No. However, you could shim the 34.9 to fit a 31.8 seattube.
