One part fat bike, one part 29er, and two parts awesome, Surly's Krampus rolls fast, holds speed, and devours corners. Surly built the frame and fork with chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. The 29 x 3-inch Knard tires on 50mm Surly Rabbit Hole rims are what make this bike truly special. These big tires offer increased traction, incredible float, and reduce the need for suspension because the large volume is plenty to smooth the trail. You'll also get a Shimano Zee single-ring crankset, a Shimano rear derailleur for crisp shifts, and Avid BB7 brakes to give this guy some trail manners.
