Right now I'm leaning towards the Specialized Rockhopper disc 29. It has the disc brakes and 29" wheels. I assume it is otherwise the same as the regular Rockhopper. The bigger wheels and disk brakes add to the price, but I think it would be a responsible way to spend my economic stimulus cash when it arrives. Also, the Disc 29 comes in a color I like more than the regular Rockhoppers; orange.
