So I have a 1997 Schwinn Mesa GS that is getting a bit old (assuming I've had it for almost 20 years, it is old). I replaced the front fork a few years ago and that required a v-brake conversion on the front end. I felt like it was an improvement but my wife would still zip past me on her newer mountain bike. Aside from that the thing is starting to wear down quite a bit and is in need of an overhaul. Is it worth trying to update it a bit where I can or am I better off just getting a newer mountain bike?
