Looks like a great community here, I'm glad I stumbled upon it.
I have a few questions, if someone can help. I just got a Trek 3900 MTB as a graduation gift. I know it's not that great, but it was free
Anyways, I have some money to spend, and I want to know what would make it perform better. I used to BMX so I'm not a complete newb, but I would like to know where money best spent would be on this bike. I mainly do single trail riding with a couple jumps, good amount of fallen trees both small and decent sized, and the occasional hills...nothing too difficult in my area. Since I've never ridden a nice bike, I don't know what is bad about my bike. I would like to spend about $2-350.
Any suggestions? fork, derailleur, anything?
