Hello, I am currently trying to get a mountain bike, and I have a pretty small budget. I usually just ride my redline bmx on dirt jumps, but I really want something that I can take on trails. I found a used trek 4300 for $160 that fits me well and rides well, but I wanted to know if I am making the right choice for the money. It is a 2005 without disc brakes, and it has an rst front fork. Here is a picture of the bike. All is in working condition.
