Superfly raises the bar for 29er hardtail mountain bike performance. This lineup of aluminum, carbon, and super-light-carbon XC rockets is more than fast. It’s the fastest.

Upgrades from Superfly 7

  • Fox Evolution fork w/CTD
  • Shimano SLX 38/24 crank
  • Shimano SLX front derailleur
  • Shimano SLX hydraulic disc brakes
  • Bontrager Race X Lite stem

G2 Geometry

Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability.

E2 tapered head tube

E2 tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the stiffness of a full 1.5" system without the added weight.

Balanced post mount brake

The brake caliper serves as a structural part of the frame, anchored between the chainstay and seatstay. It reduces weight by eliminating the need for a chainstay/seatstay brace.

Closed convert dropouts

Hardtails offer the robust performance of a closed thru-axle system with the convenience of a system that can accept 142x12 or 135x5 rear spacing.

Alpha Platinum Aluminum

Trek's premium alloy, formed into sophisticated tube shapes for maximum strength and minimum weight.

29" wheels

The gold standard for smooth, stable riding. Bigger wheels carry more momentum, roll over obstacles more easily, and offer greater stability and more traction than smaller options.

Press-fit bottom bracket

Press-fit BB increases pedaling efficiency and allows for a stronger, stiffer frame structure.

Fully integrated head tube

A fully integrated head tube eliminates the need for headset cups, reducing overall weight without sacrificing performance.

2x10

A 10-speed cassette and 2-ring crankset deliver a full range of useable gears, with less weight and easier, smoother shifting.

15QR

A 15mm front thru axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.

142x12

A more robust and confidence-inspiring rear thru axle, about 35% stiffer than an open dropout design. And now, a thru axle wheel change is actually quick and easy.

Climb-Trail-Descend

CTD gives you three suspension adjustment options: Climb, Trail, or Descend. It’s a simple, intuitive, high-performance system available on select Fox shocks and forks.

Suspension lockout

Lock out the suspension fork for efficient riding on smooth terrain.

Extended size range

A wider range of sizes than the industry standard provides more option for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.

Gary Fisher Collection

Innovative bikes imagined by Gary Fisher, built by Trek.

Hydraulic disc brakes

Ultimate control and stopping power in all conditions, including wet and muddy.

Internal derailleur routing

Route your derailleur cables through the frame to keep your bike running smooth and clean.
