I was looking around at some Diamond Backs at a sporting goods store, and I saw the Overdrive V. Then I saw it was a 29er and it was only $500. My question is does anyone know if it would nake a good light trail bike? My Trek 3900 does awesome on the trails and it looks like the Overdrive's components are only a step down from the Trek. If it wouldn't make a good starter does anyone have advice on what would?
