I have 2003 Litespeed road bike and since I got it I started to replace a lot of things on it. As a result I have some parts lying around and because I want to learn as much as possible about bike maintenance I thought it'd be a good idea to build a bike from these older component.
Obviously I will need a frame to do this and I think a used older / cheap steel frame will do it. Because I don't know anything about bike building now, I have a couple of very basic question:
x) is it possible to put a complete Ultegra 6500 groupset on an older steel frame?
x) what should I look for in a frame to make sure it will be compatible with my newer groupset?
x) Is it possible to install a modern stem / handlebar on it?
x) Is it possible to install an early 2000's mavic wheel?
I just want to hear some opinions and starting points and I'll be fine from there.
