I question the 28T chainring with 52T. I'm not sure if a Campy derailleur is happy with that big of a jump. Joe did something on Amy's bike to give her low, low gears. He and I had a discussion on these same lines a few weeks ago but I don't remember the details.

While a trip to CA is always nice, I'm sure he can advise and then supply parts. I know that SRAM or TA was in the discussion.
