(If I get some the parts and descriptions wrong, sorry I'm a newb)
So I was a very enthusiastic newbie a couple weeks back. I began riding my bike more and even commuting to work. Beginning last Thursday I was riding home from a great day at work in beautiful 60 degree weather when the chain on my mid 90s Trek 850 MTB began skipping. It usually skipped when I stood on the pedals for more power, but this day it was skipping about every 4 turns of the pedals. I made it home and looked at the bike, but didn't see anything outright wrong. So I went inside and began cooking dinner.
I took my bike into the LBS and they saw the teeth were worn down and 5 were broken off on two of my three front chain rings. That and a much needed tune up would cost at least $100. He also told me about their trade in program and that I could maybe get a decent new or used road bike (something I eventually want to get) and they could work on a deal with me. I have also had an offer to buy a used roadie from another person within these forums.
The only problem is that my girlfriend and I are closing on a new house in a month and a half and need to save a ton of dough for closing, and some vital appliances like a fridge (to keep beer cool) and a washer & dryer (to wash bike clothes after long rides). Basically I cannot spend a ton of cash right now, and do not want to make large purchases on my credit card.
Well it has been since Thursday when I last rode a bike and I do not feel the same anymore. I loved commuting and began to lose some weight too. I also wanted to take some weekend rides and my girlfriend wants to get into riding casually. I am feeling down about the whole thing, want to bike again and continue my quest to commute, lose weight, and just be on a bike.
What would the collective wisdom of BikeForums have to say? Any alternatives I could do? Should I bite the bullet and buy a new (maybe used) bike or fix my old one?
Thanks in advance, sorry for the long description.
