Looking to spend about 300.00 on a bike and I'm lost. I am now 35 and haven't done much riding since I was about 16 (when I stopped). Back in the day you bought one bike and it was good for everything. Jumping, flatland, street, and racing. Now I don't know where to start. I was thinking either Dirt Jumper or a Race bike. Ideally a long top top tube and 4130 Cro-Mo F&F. I may be old, but I still can tear it up a bit. Occasionally, I will goof around a bit with my son's flat land bike, but I am more into jumping and possibly racing again. Can anyone recommend a good sturdy bike for jumping that I may take out to the local track? Keeping in mind I am 5' 11" at 175lbs. I don't care if it my jumping bike is a bit heavy.

Watch Craigslist. I see all kinds of deals pop up on there.
