Yet Another so called platform? Yikes. But Wait! There's a reason: 29+ equals fun. Surly's new Krampus frame is built specifically for 29x3" tyres on 50mm rims. 29+ offers fast rolling inertia with traction to spare, and even some float on loose terrain. 29+ isn't just a big wheeled version of a fat bike, it's the logical progression of 29". Rip trails or ride where there are no trails. Do it all with a shit-eating grin. Now more than ever, is the best time to be Surly

"The Krampus is a mountain bike..... with more traction, a smoother ride, and better geometry for high speed. The benefit over a fat bike is that this bike uses normal stuff and it doesn't HAVE to be built like anything special. The bike is nimble like a regular 29er, but confidence inspiring like a fatbike."
