BEST FOR: RACERS
Every major snow-bike race in 2012 (including the granddaddy, the Iditabike) was won aboard one of these Alaskan race rigs. The Fatback is blinged out with a house-branded carbon fork and carbon wheels (which are a pound lighter than the competition’s) and 45Nrth’s siped Hüsker Dü tires. Tons of standover and minimal heft (just 27 pounds) make it feel more XC than XXL. For going fast when it’s freezing, there’s no better choice.
