It's right for you if...

You want one bike that's fun to ride on every trail, and you want upgraded parts, like a smoother DebonAir spring fork and a completely tubeless set-up for less weight and more traction.

The tech you get

A light yet stiff alloy frame, a 140 mm RockShox fork with a DebonAir spring for better small-bump compliance and a FOX shock. A 1x12 SRAM NX Eagle drive train with a wide gear range. Plus, Bontrager Line Comp 30 wheels with tubeless tyres and a dropper post.

The final word

Fuel EX 7 is a great all-around trail bike for a wide variety of terrain. It has upgrades where it matters most, like the suspension, drive train and tubeless-ready Bontrager wheels.

  1. You get more traction and control with upgraded parts you won't outgrow immediately as your skills progress
  2. You're getting a solid trail bike that's ready for anything you are
  3. The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  4. Wide Line Comp 30 wheels provide more tyre support, so you get better traction and control
  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


Features

Will my bike have a curved top tube?

Will my bike have a curved top tube?

Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

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.

Straight Shot w/Knock Block

Trek's Straight Shot frame design optimises the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
