Iknow people have done this in the past, maybe not to the extent I am about to list, or maybe that someone might be interested in doing something like this too.
***Disclaimer - This isn't a thread for the hardcore CV's that want vintage to stay vintage. I have some projects that I am keeping a vintage bike as vintage as possible, but I also enjoy new bikes and tech. So I want to try and mix them someday.
Frame - Something vintage steel.
Fork - Threaded carbon fork (Nashbar has one)
Stem - Carbon Threadless (using an adaptor, Nashbar also has)
Bar - Carbon drops
Seat post - Carbon
Saddle - Not sure. Light weight Brooks Swallow would be fitting, or a light weight, yet comfortable, modern saddle.
Wheels - Something light weight
Components - Depends on what would fit. As light as possible, 9/10 speed, brifters, etc.
Basically, the plan would be to repaint the frame, only if needed, to as original as possible, but not a show bike look. Then build it up. This is just an idea that I am kicking around at the moment. Was thinking about trying it out on a 89 Raleigh Technium Pre, but was more trying to modernize/black out the bike as much as possible, but still keep the downtube shifters. Thinking about waiting for a bike that is a little more vintage.
So what are the feelings. Any recommendations you can give? Not sure that I will be doing this project any time soon, but starting to think about it to start planning it.
