2021 Trek Fuel EX 9.7

Fuel EX 9.7 is our most affordable full suspension carbon trail bike. It pairs a lightweight, smooth-riding frame with a beefy 140 mm FOX 36 fork, SRAM NX Eagle drive train and powerful 4-piston brakes for a fast, fun mountain bike that's a ripper now, and ripe for upgrades later.

It's right for you if...

You want one carbon trail bike that can take on every adventure, from flowy singletrack to the gnarliest descents and most brutal climbs. You don't mind sacrificing a little on the parts so you can get the best frame right now.

The tech you get

A lightweight and stiff full OCLV Mountain Carbon frame with internal storage, a 140 mm FOX Rhythm 36 fork, 130 mm of rear travel with a FOX Float Performance rear shock with Trek's efficient RE:aktiv damper, a wide-range 1x12 SRAM NX/GX Eagle drive train, a Bontrager Line dropper post and powerful Shimano 4-piston hydraulic disc brakes.

The final word

Full suspension control on a lightweight and trail-tough carbon frame makes for a fun and fast ride. It's rugged enough for rowdy descents, but still spry for lively climbing and accelerating.


The Walkthrough

favorite_borderWhy you'll love it

  1. Don't confuse the Fuel EX 9.7 with other value carbon models on the market – this bike provides an outstanding frame and suspension, with a workhorse drivetrain and wheels
  2. A sleek internal storage compartment gives you a handy spot to stow flat fixing supplies or gear
  3. Bigger, stiffer 36 mm fork stanchions won't flex, so you can push harder with more precise, confident steering that helps you stay on your line
  4. RE:aktiv is smarter, more efficient suspension. It gives you firm pedalling support that instantly gives way over bumps
  5. We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝ and sizes M to XL get 29˝ wheels
