I'll start by being honest, I am hard headed and wanted to figure this out on my own. CAN'T! FAILED! NEED HELP! PLEASE!

I've been in the process of converting our Litespeed tandem from Ultegra 9 speed (bye bye!) to New Campy Record 10 speed for the past few months. I bought

New Campy 2014 Record QS shifters (work great)
New Campy comp triple long cage rear derailer (works great)

4 Front Derailleurs all new


#1 Campy Racing T with a 32mm
My tandem is 35mm. I thought that the clamp came off but it does not. So this one is a straight up mistake to learn from. All the rest are braze-on

#2 Campy Centaur 10 speed triple
I thought for sure this one would work, but I was wrong. The right side of cage hits my crank arm. If I adjust the high limit to where the cage does not hit the crank, it will not shift to the big ring regardless of where the chain is on the rear cassette. I believe this is because the cage is too wide. The front ring is a 53 tooth and I have Logic cranks.

#3 Campy Centaur 10 speed double
I bought this because the cage is narrower and it did shift on all three rings without hitting the crank. BUT the cage is not long enough and if I am in the high gears (shorts cogs) in the back and low gear in the front the chain rubs on the bottom of the front derailleur cage. If I adjust the height of the front derailler down then the right side of the cage hits the big ring and cannot pass by.

#4 Campy Comp triple 10 speed QS
Again I thought this would be gold, but it is the exact same cage as #2 Campy Centaur 10 speed triple. I didn't even try it because it's brand new and I want to return it.


My magical Ultegra derailleur FD6503 works and does not hit. It does rub in low gear in front and highest (fastest) 5 or 6 gears in back. It does jump over the big ring sometimes, but even then it does not hit the crank. I don't like having one different brand part on my bike and I don't like that the indexing is not the same as campy, but I can limp along this way until I get to the bottom of this.

ANY help please???
