I am building an ultra budget race bike a.t.m and have gotten an unused 2004 (i think) Centaur 10 speed groupset from work for pennies. The only problem is a missing rear derailleur. I can get my hands on a 2011 xenon rear derailleur really cheep, will these work together?

Thanks for the help guys

Ask in Mechanics.

I recall reading that all Campy 10s components are compatible.

Thanks guys

It will work.
