I have an Ultegra/105 Bianchi, 50/34 & 12/25. I'm thinking about possibly changing to 52/39 (or close to) and maybe 11/28 on the back. How big a job are you talking here, I take it a good bike mechanic can do this? ( I ask as I left a previous yoke into my LBS to get a new casette on and it was never the same again and I'm going to have to look about for someone to do if for me). Would those gear ratios be ok? I take I should stick to Ultegra/105 (or better) components
