What AEO said.

My first ride (Oct, 2009) with new Chorus 11 components: threw the chain off the inside (couldn't make it do it again); shifting from the large to small ring it seemed to get stuck (chain rubbing on FB). I had been using Shimano Ultegra previously and wasn't used to Campy. It's like Campy has a couple of clicks in the shifter to get from large to small rings. I chalked up these two things to new user error.

Things have been working fine since then except the chain has gotten thrown off the small ring twice in the last couple of weeks. I need to check the limit screws.
