I'm new to the Campy Record 10 speed world. I have a newly built Moots road bike with Campy triple
(30, 39, 53) and 11-23 cassette. Under load, the bike performs flawlessly when in the smallest chain
ring. When in the middle chain ring and in the middle of the cassette, the chain either skips (but
stays on the cog) or jumps to the inside chainring or completely off. Again, this only happens under
load (sprinting/Climbing). Since the frame and parts are all new, I'll trust that frame alignment is
not an issue. The derailleur hanger appears to be aligned. When in the largest chainring and
smallest cog, the rear-derailleur bottom jockey wheel is pulled slightly forward out of perfect
vertical alignment with the upper jockey wheel. Derailleur adjustment seems to be spot on. Do you
have any insights into what the problem could be? This is a very un-nerving and unsafe situation as
I don't feel comfortable getting out of the saddle and torqueing up a hill when in the middle
chainring for fear of the chain jumping off.
