The Walkthrough

favorite_borderWhy you'll love it

  1. A full OCLV Mountain Carbon main frame a stays make for a ride that's light on the climbs and trail-tough on rough descents
  2. RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
  3. It doesn't box itself into a category: Fuel EX brings trail bike plushness with an XC race bike feel for our most versatile mountain bike whip
  4. It's great for riders who don't want to do just one kind of mountain biking, but want to explore everything from XC marathons to epic descents
  5.  Internal cable routing and Control Freak Cable Management make it easy to spec with quality trail bike tech, like a dropper post

"Way ahead of the pack"

"The faster our test riders pushed, the better the bike felt, inspiring more confidence than a bike in this suspension category should. Fuel EX makes a strong argument for itself as a do-it-all trail machine that is pure fun to rip."

"Lightning fast and wildly fun"

"Trek has elevated the Fuel EX's performance even further. This latest iteration feels just as quick on the climbs, but when it's time to descend, it's less phased by steep and technical trails than ever before."

"A bike with fire in its belly"

"A trail hammering speed machine, lightweight, incredibly well built, and so beautifully constructed. A genuinely quick and balanced trail bike that's bang up to date in angles and ride dynamic."

"Right on the money"

Control Freak Cable Management

The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.

Boost148/110

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

G2 Geometry

Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.
