Diamondback Overdrive Comp 29er Mountain Bike - Nashbar Exclusive

I picked up the Diamondback Overdrive Comp and love it. I ride on trails that are either soft sand or hard rock for the past 6 months with no failures. Depending on your inseam you can do either a Large or XL.. I have a 34 in inseam and the XL was the way I went.. may be just a little on the big side for me as I have about an inch and a half clearance off the saddle, but no issues hopping off so far.
