Thanks to everybody for the help and information. Turns out that my Logic Ritchey cranks are very straight up and leave zero tolerance for a triple FD to travel far enough to get on the big ring and clear the inside of the crank arm. I bought a Campagnolo Racing T crankset off ebay. The Racing T right crank arm curves out .090 more than my Logic/Sugino crank arm. This allows my FD to shift properly onto the big ring and not hit the crank. I just didn't realize how much the Campy arm curves up and how straight my logic crank arm was.

Current setup

Campagnolo Comp triple QS front derailleur
Racing T crank arm 30-42-53
Ritchey logic bottom bracket 120mm
Campagnolo QS 10 speed record shifters
Comp triple rear derailleur
Ambrosio Campagnolo Cassette with shimano splines 12-28. I highly recommend this


In the process, I discovered that the bearings in my bottom bracket are not good. It is a Ritchey logic 120mm. I can't find any 120mm bottom brackets on ebay that are like mine. Any suggestions? I did find 118mm and 122.5mm
