I accidentally went to a sporting goods store and bought a bike. It is a diamondback Coil EX Frame. I know that everone must think that was dumb, but hey I'm new. I'm having all kinds of problems, mainly due to the fact that the parts aren't designed for the type of riding I'm doing. Is the frame good enough just to upgrade, or is it just better to buy a new bike. Keep in mind I know it was a bad move.
