From the continued web surfing research, it look like the front der. I have is the same as the race triple version. I have been told by others that campy didn't make a compact specific triple? I have had the frame for over 10 years and have been using a centaur double front on a 10 speed 53/39 chorus crank with no problems. I'm told campy published a table explaining front der. braze on height with compatible chain rings. The triple chorus 10 speed crank and bb are the right match. Not sure what else to do except possibly explore buying smaller chain rings?
