Trek announced a revamp of its most popular trail bike, the Fuel EX. Fuel EX has always been an exceedingly capable option for riders who want a single mountain bike that rides almost anything. Now, it’s even more versatile and adventure-ready, thanks to updates in frame design, suspension, and size range.

Updated frame, updated suspension

All Fuel EX models now feature a longer-travel 140 millimeter suspension fork with 130 millimeters of rear suspension travel. This combination gives riders more confidence on bigger hits without sacrificing climbing efficiency.

Fuel EX’s updated geometry strikes the right balance of capability and efficiency. The new models are longer and slacker than previous versions, making them feel more stable on descents. They also have a steeper seat tube angle that puts the rider in a more efficient pedaling position.

The new frames also feature a fixed lower shock mount that makes for stronger chainstays and increased pedaling efficiency. As with previous models, frame details like Mino Link adjustable geometry and Control Freak cable routing make it easy for riders to run a clean, customized set up.

OCLV Carbon Fuel EX models now have a frame-integrated storage compartment that lets riders easily store essentials like a tube or tools without the weight or hassle of a pack.

In addition to the new frame and suspension setup, all Fuel EX models come equipped with trail-specific specs like dropper posts, wide-range 1x drivetrains, and grippy 2.6-inch tires. Most models feature our RE:aktiv-damped shock. Select models feature RE:aktiv with Thru Shaft for even more traction and confidence.

A better fit for more riders

All Fuel EX models will now be offered in size XS for a full-size run of XS, S, M, L, XL, and XXL. All models will also be available in at least two colors.

“Rather than offering limited models for women, we’re offering more choices for everyone,” said Mountain Bike Director John Riley. “Whether a rider is male or female, short or tall, or anywhere in between, Fuel EX offers the perfect fit.”

Fuel EX models also come with the best-fitting wheel size for each frame size. Size M and larger bikes come with 29-inch wheels. XS frames come with 27.5-inch wheels that are easier for smaller riders to control and offer better standover clearance. Size S riders get to choose between 27.5-inch or 29-inch wheels. This is because our research shows that riders of this size tend to be evenly split on wheel size preference.

Available in Project One

Riders can customize their paint and parts for their Fuel EX 9.8 and Fuel EX 9.9 models to their liking through Project One.

Flagship Fuel EX 9.9s

The marquee models in the Fuel EX lineup feature full OCLV Carbon frames with integrated storage, FOX Factory suspension, carbon components, and the best drivetrains available.

Fuel EX is available in a range of models through Trek’s global network of retailers and on trekbikes.com. USD Pricing ranges from $2,099 MSRP to $7,499 MSRP with the Fuel EX 5 and the Fuel EX 9.9 at either end of the spectrum.
