I am new to road biking and just bought a bike on craigslist. I think I was ripped off because when I went to the local place to have it tuned up, they told me I needed a new fork, brake, pedals, and back wheel. I paid $100 for the bike, and the repairs are $110. I tested it out but not very far and I feel like such an idiot right now and want to cry, but I didn't know what i was looking for as far as damage. I am fine with spending $200 for a decent, entry-level, first road bike, I guess I am just looking for a response from experienced people about this. It is a panasonic sport 500 17" (i am a small woman). Do I need to bury my head in shame for this!?! It almost turned me off of trying to start biking altogether.
