Overview

It's right for you if...

You want a full suspension trail bike that prioritizes suspension and shifting performance over a more expensive carbon frame.

The tech you get

A light and stiff alloy frame with 150mm FOX Rhythm fork with Float EVOL air spring and GRIP damper for small bump compliance, plus a FOX Performance Float X rear shock. A Shimano XT 12-speed drivetrain for snappy shifting, and tubeless-ready Bontrager wheels. Plus, new adjustable geometry that lets you take control of your setup.

The final word

For the rider who doesn't want to be limited on the trail, Fuel EX 8 is ready to handle everything. Its progressive trail geometry is built to keep you charging, and upgraded components are they cherry on top.

The Walkthrough

favorite_borderWhy you'll love it

  1. This bike is built to take on the singletrack, with modern geometry that's evolved to handle the rough and rowdy
  2. You'll get upgraded components where it matters most, with 12-speed XT shifting, and a rock-gobbling FOX Rhythm 36 fork
  3. With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
  4. We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels
  5. Guided internal routing, universal derailleur hanger, improved hardware, and a threaded BB make maintenance a breeze

Pinkbike's 2022 Mountain Bike of the Year

"This is a bike that could be used to head out for a big meandering backcountry adventure one day, roll up to the starting line in a local enduro race the next, or even head into the bike park for a lap or three without missing a beat."

"Our favorite Trek"

"Fuel EX proved itself a happy climber. From slabs to roots and square-edge hits, the Fuel EX handled it masterfully. A damn fine trail bike right out of the box, no matter your riding style."

"Fuel EX is a masterpiece"

"Fuel EX absolutely devours chunky terrain while still retaining the ability to tractor up steep climbs. I have become convinced that a bike with long, stable geometry and mid-level travel really can provide the best of both worlds."

"Ready for anything"

"Fuel EX's geometry feels ready for just about anything. There's plenty of traction for climbing and a nice fluttery feel on descents, calmly smothing out the trail chatter."

Features

Internal Storage

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

Watch the video

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Learn more

Slack or steep, the choice is yours

Install angle adjust headset cups (sold separately) to tweak the 64.5-degree head tube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height.

How it works

Adjust the sus for full send

Adjust leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don’t want to bottom-out, or when you want to run a coil shock.

Size-specific stays

Size-specific chainstays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders.

Business in the front, party in the back

Craving the nimble ride of 27.5˝ wheels but don’t want to sacrifice the speed of a 29er? No need to choose. Fuel EX is mullet-ready, just throw Mino Link in high, toss on a 160mm fork, and get ready to party.

New frame, new possibilities

New frame, new possibilities

Forward-thinking frame design opens possibilities for riders who want full customization. A bigger seat tube lets you roll with a beefier, longer dropper post, and broader shock compatibility plays well with tons of aftermarket shocks, including coil.

Complete Tubeless System

Complete Tubeless System

Mino Link adjustable geometry

Mino Link adjustable geometry

Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.

Threaded bottom bracket

Threaded bottom bracket

More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.
