I am having a cyclocross frame with top tube cable routing (EM2 tubing) built with full Campy Choros Triple (30-40-50 with 13-26 cassette) for summer commuting. Because Campy does not make a top pull front derailleur my LBS is going to try a Shimano XTR front derailleur. I saw a picture of a Pinarello Cross with full Record and a Deore front derailleur. Mabe it was marketing hype. But maybe it works? All this because I do not want to have to use one of those goofy looking pully gizmos on my seat tube. If this does not work I am prepared to go full Shimano XT with flat bars. What have others done to get around the problem that Campy does not make a top pull front derailleur ?
