To open myself up to ridicule, I'm putting a bunch of new parts on a 80's something Univega Sportour. All the parts where bought on sale from Nashbar and Harris cycle . I'm using the bike to learn how to wrench. So far - I think I'm done buying - I have $600 dollars in it. But, that includes almost $200 in tools which I will own for the rest of my life. The way I look at it, tools are cheap in a world where bicycle tune-ups cost $50+. Play with yours, enjoy, learn how a bicycle is put together. Attached is what I started with, a very rusting Sportour.
