The 2014 Surly Krampus is the evolution of the 29er. It’s not a fat bike. True, its got 3 inch tires on 50mm rims. But where fat bikes are really designed for slow-speed crawling, Krampus’s frame has been designed with a long toptube and as short a rear end as we could get away with given the wheel/tire size. This, when combined with the big, wide tires, results in a mad amount of rolling inertia and grip. It rips and responds well to body English. The big tires also offer a bit of suspension-like cushion. Krampus is a trail bike that also tackles all kinds of terrain. Krampus lives somewhere between bushwhacking, speed racing, and back lot dirt track riding, and all this makes it just plain fun to ride.
Krmapus’s hub spacing is standard 100mm front and 135mm rear, with rear-loading horizontal dropouts that accommodate a derailleur and single ring/cog drivetrains. It’s got clearance for disc rotors up to 185mm and is designed to run a high direct mount standard front derailleur. This type of derailleur will allow the most clearance at the tire. Even though there is no need for the sort of frame offset you find on our Pugsley and Moonlander models, chain and derailleur clearance at the tire remains a serious consideration. If you plan to use standard width rims and tires, you’ll be able to run a normal mountain triple crank. However, if you go with our 50mm Rabbit Hole rims and 3 Knard tires (and why wouldn’t you?) then plan to use a 1x or 2x crank…a triple simply won’t clear the tire. For best chain/tire clearance, we recommend either a Surly O.D. 2x crank or a 1x system. Other brands’ 2x cranks will work but may cause some chain-on-tire rub in the easiest gear combo.
Got all that? O.K., then. Give it the juice and hang on.
