    Shimano FD, Campy shifter ...will it work ?

    Can use use a Shimano triple front derailler (FD-6603) with a Campy chorus shifter? Or to put it in another way, can you replace a Campy triple FD with a Shimano triple FD? Thanks in advance.

    The problem is not with the Campy. shifter, it is with your crankset. If your Campy crankset is a 52-42-30 , the FD-6603 (made for 52-39-30) won't work, the back lip/flange of the dérailleur won't clear the 42T, and if you re-adjut it to clear the 42T, it will be to high for the 52T. Obviously, no problem if your Campy crankset is 52-39-30.

    I started to take exception to this since I have a Specialized Allez Elite which has a Sugino triple crankset, 52-42-30, and a Shimano 105 FD. Then I realized that it is 9 speed and Shimano offered a 52-42-30 crankset at that time. Now, with 10-speed, they offer a 52-39-30 crankset. Are the FD's that much different for 9 speed vs 10 speed? I am surprised that they would change the chainring sizes this way just due to the chain getting a little thinner.

    Thanks,
    Ted

    Campagnolo front shifters are compatible with all front derailers. This is one of the chief benefits of the Campagnolo brifters.

    Actually, the width isn't much of an issue. It's really about the middle/big jump.

    The so-called "9-speed" triple front derailers are optimized for a 10 tooth jump middle/big.

    The so-called "10-speed" triple front derailers are optimized for a 13 tooth jump middle/big.

    Chose on the basis of you chainring sizes, not the number of speeds on your cassette.
