It doesn't matter if you're climbing or descending, you'll charge every trail on Diamondback's Sortie 1 29er. Its lightweight aluminum frame rocks Diamondback's Knuckle Box rear linkage to enable you to do some serious all-day rides. Long ride or short, for maximum control and confidence, this big-wheel rig has 4.5 inches of front and rear travel courtesy of Fox. Hauling it down are a sweet set of Shimano hydraulic disc brakes which provide consistent, powerful stopping control. Shimano takes care of the shifting as well with their reliable 30-speed drivetrain, and you'll love the durable wheels and sticky WTB tires.
