When looking at go-fast XC bikes, low weight and responsive speed make up a huge portion of the whole package. Trek's Superfly 9.7 nails it. Backed by countless wins, it boasts a full-carbon frame and 100mm Fox 32 Float fork. That's only half the story. To win, you have to ride, and the Superfly has the geometry, handling and specs to crush every section of dirt. Proven and loved G2 geometry is quick and confident, whether racing or just pinning your favorite loop. For gearing, you've got 2x10 Shimano with an XT rear derailleur, and you're spinning on tubeless-ready Bontrager wheels. Shimano discs temper your speed and Bontrager controls pilot you to the win. Superfly: It's the whole package.
