I did a 180. Changed my mind. Reversed. I kept all the Campy and just installed new 12-30 cassette. Well, also new Campy cables and Torelli housings. Wasn't convinced using an FSA SRAM or Shimano crank would work all that well. It sure does shift well. And it's such a light bike and good climber that the 30 in back with 34 up front should be ok for most of the hills I climb. I'm 66 with a lot fewer watts than I had when I was 26, but this should be fine.
