I bought a 70s (or maybe 60s) bike for my mom for $20. It's a Galaxy II, 26". The frame is in good shape. The components aren't as rusted as they could be.
this is my first time restoring a bike, and I could use the experience. There are 2 things I'm confused about.
I got the front brakes working pretty good. But the back brakes are weak and stiff. I tried lubing the cable and clearing the rust off the metal, but that doesn't seem to have done much good. Maybe the spring needs to be replaced. any advice?
Also, both gear adjustment pegs are stiff as hell. So again, I'll lube up the cable and go from there.
I don't know whether I should try to fix these things or buy new parts. Any advice is appreciated.
also, the chain is all rusted up, but it's not stretched out at all. Do rusty chains necessarily need replacement?
