Fuel EX AL is an aluminum full suspension mountain bike frameset that makes the perfect start for a capable trail bike build. Trail-tough alloy tubes, the latest in Trek trail bike frame tech, and a 130mm of travel with a RE:aktiv shock make it a great choice for riders who want a bike that can handle everything from serious all-mountain riding to endurance races.

• RE:aktiv is firm when youre pedaling and plush over bumps
• This bike is perfect for shredding singletrack, hitting drops, and pushing your limits on the longest days
• Control Freak cable management makes it easy to run any combination of controls, like front brake on the right or internal droppers
• We expanded our size range from XS through XL to ensure a better fit for all riders

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 dont 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.

RE:aktiv

RE:aktiv technology gives you firm support for efficient pedaling that instantly gives way for smooth control when the trail turns rough.

Straight Shot w/Knock Block

Treks Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. Youll be able to push harder and stay more planted on your line when the going gets rough.
