I'm thinking about rebuilding my Gran Sport with indexed shifters and lighter wheels, etc. My local bike shop says to forget it and buy a new bike (last year I bought a Cannondale Synapse carbon 2 from them--they don't seem to understand 34 years of attachment). I've been searching this forum for specifics on whether, say, a Shimano groupset would fit this frame and I did call Performance Bike who told me I need to take it to a frame shop so the 10speed gear set will fit (the bike shop says to just shove it in and I have looked at Sheldon Brown's site about cold setting the frame).
In addition, I have Campy hubs that I may keep if they are in good condition, however I'd still like to put on lighter wheels and spokes--does this make sense? Money's not the major issue--it's more of an emotional journey, with the end result, hopefully being a nice upgraded ridable bicycle.
I'd appreciate any input, or direction to relevant posts that have already dealt with this issue.
