One part fat-bike, one part 29er, and two parts awesome, Surly's Krampus Frameset lets you build a fast and fun bike that rolls over anything and everything. Surly crafts the frame and fork from reliable and great-riding chromoly and provides a long top tube and short chainstays for a playful and smooth ride. This frameset accepts 29-inch wheels and tires up to 3 inches wide for outstanding traction and control. MDS dropouts allow you to pick your favorite drivetrain, with geared, single-speed, and thru-axle options. Plus, you get frame reinforcements in all the right places and all the braze-ons and details needed so that you can handcraft your dream bike.
