Trek's Superfly 7 is ridiculously fast and racy, yet at the same time, a confident, capable daily driver. Chalk it up to Trek's Alpha aluminum frame with a 142x12mm rear axle, the proven G2 geometry, and the 100mm Fox 32 Float fork with a 15mm thru-axle. They end up being greater than the sum of their parts for a ride that is fast but not twitchy, stable yet not sluggish, and mind-blowingly fun to hammer on. We swear it violates physics. Specs wise, check out the Shimano 2x10 gearing with an XT clutch derailleur that keeps your chain quiet. Race Lite components and tubeless-ready Bonty wheels and tires round out the specs. The Superfly 7 is fantastic fun, it's one of the biggest reasons we ride bikes.
