I ride a 1979 trek 710 full 531 bike. It's time to replace some drivetrain parts as they are old. Been riding it over a decade now.

I'm thinking of spreading the frame and doing a full upgrade. STI, new cranks, brakes, wheels. Even new shallow drop bars.

My question isn't one of value. The frame kicks ass and I can't afford a new frame set like this. I just like the bike and working on bikes and I think this thing would be nice upgraded.

My question for you classic minded guys is am I committing some sort of historic crime? I wrestle with selling this bike intact to a person who likes classics and getting something like a Soma ES almost weekly.
