Nashbar AT2 Mountain Bike. Find adventures on the path, pavement or trail with the Nashbar AT2 mountain bike. This 26 hardtail mountain bike has a 24 speed drive train to give you plenty of gear ratios to get a good head of speed on the flats, while making the hills a little more manageable. The Suntour fork has 80mm of travel to take the sting out of the trail or road, and the 26 wheels and big, beefy tires can handle pretty much anything you put in their way. If you're looking for a bike that can anywhere and do anything, this is it.
