after 13 years of riding (some competitive), i realize basic maintenance will prolong groupo's life......
I had replaced the ultegra's chain around 2k and the 2nd chain was gone again at 3900mi.
I'm doing the same maintenance on my Campy drivetrain as i had done with Ultegra. The campy by my watch is lasting much longer.
