I have a mid 80s Fiorelli(6 speed cassette) bike I am restoring. My plan is to ride the bike some. It won't be my main bike. It currently has a Campagnolo Triomphe crank. I would like to cold set the rear to 130mm and upgrade the shifters to a new 10 speed group with ErgoPower Shifters. (I really don't want to go back to downtube shifters.) Will the Triomphe crank work with the newer 9 or 10 speed group sets? The main reason I want to keep the Triomphe crank is that it will accommodate smaller chain rings than 39.

Thanks
