Bicycle Mechanics - Campy derailleur compatability question

Hmm should have posted in here from the beginning. This should be a relatively simple question I hope. Is there any forseeable difficulty in running a Daytona FD intended for 9-speed use with a 10 speed set up (rest veloce)... I need to buy a clamp on for a steel frame and I am doing it on a budget and there don't seem to be many 10-speed clamp ons in in 28.6mm. thanks.

Seems I am the only one posting here. Well i discovered that the cages on 10 speed fronts are narrower than 9s because the chain is narrower and I guess the chainwheels are also a little different. Makes sense when you think about it. however I think the difference is half a millimeter in width and alas there should be no problem running an older derailleur however I think this may no longer be a problem. I do ride vintage but I think I decided to say screw messing around (because I haven't even aquired a proper vinatage frame to run my group on) and I am going to buy a brand spanking new Vitali (one of two left which are both my size (64 c-T) at my LBS and which will no longer be carried (or produced???)). They are full lugged steel and sell for 425 CND thats about 350 US. Not bad for a brand new Italian frame made from columbus which is equiped with a braze-on FD mount.

I just thought maybe the cage would be narrower on a 9speed or something.. maybe???

Assuming you get the correct clamp size and you have the correct bb axle length for a double, there should be no problem using a 9 speed frt derailleur on a bike with a 10 spd cassette. The differences in the front chainrings are not detectable by your frt derailleur.

I think it will work. Campy lists 10/9 der. and 9/8 der. The width of the plates is probably a little different, this would be an issue with Shimano as they have 3/4 steps. With Campy there are many small steps so the trim is not a problem.
Truthfully the issue should be double/triple as the back plates are different, if that is a change you are making.
You can get Centaur in 28.6/10spd or you could get a Veloce braze on and Clamp: Quality #DP6206 (you would have to get the clamp from a bike shop)

Thanks! I saw a daytona 28.6 go on ebay for 22USD, I let it pass, I guess I can get the clamp for the daytona braze on coming in the mail if need be. Alas I think I have convinced my girlfriend that buying a 425CND brand new lugged steel frame is a good idea so it shouldn't be a problem anymore.
