I'm talking about my schwinn varsity road bicycle.
My rear derailleur broke today and these components are cheap. I'd like to get a new bike, but my college student budget won't allow it. I was thinking of slowly upgrading parts until I've got a respectable bike.
So, I'm lost with all of the compatibility issues involved with changing derailleurs and speeds on the bike. Right now it's a 7spd's in the back and 2 up front. I'd like to get ten in the back and a triple up front. I'll need new shifters, because the current ones aren't really road bike shifters. They're on the handle bars, on opposite sides of the stem.
So what am I going to have to replace and with what parts specifically? I'd like to do this as cheaply as possible.
