Krampus 29&Quot; Trail Mountain Bike - 563594516
Krampus is the evolution of the 29er. Its not a fat bike. True, its got 3 tires on 50mm rims (we call this combination 29+). But where fat bikes are really designed for slow-speed crawling, Krampuss frame (geometry, tubing diameter/thickness) 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.
Krampuss hub spacing is standard 100mm front and 135mm rear, with rear-loading horizontal dropouts that accommodate a derailleur and single ring/cog drivetrains. Its 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, youll 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 wouldnt you?) then plan to use a 1x or 2x cranka triple simply wont 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.
