When looking at go-fast XC bikes, low weight and speed are the main factors. Trek's Superfly 9.7 nails it. Backed by countless wins, it boasts a full-carbon frame and 100mm Fox 32 Float fork. And that's only half the story. To win, you have to ride, and the Superfly has the geometry, handing and specs to crush every section of dirt. Gary Fisher's G2 geometry is quick and confident, whether racing or just pinning your favorite loop. For gearing, you've got 2x10 SRAM with an X9 rear derailleur, and you're spinning on tubeless-ready Bontrager wheels. Shimano SLX discs clamp down your speed and Bontrager controls pilot you to the win. Superfly: It's the whole package.
