The Fuel LX 9 XT is a trail bike for serious off-road riding that won't shy away from even the most daunting descents. Thanks to the combination of an adaptable Alpha NEXT Platinum aluminum frame, Fox Factory 38 fork, and DHX2 coil shock (160 mm rear travel, 170 mm front travel), you can tackle even the steepest, rock-strewn trails with confidence. The Shimano XT Di2 wireless shifting system is durable, precise, and weighs almost nothing. What's more, you can customize it to suit your preferences. The XT M8200 four-piston brakes boast excellent braking power modulation and will stop you on a dime.
Customize your bike, hit the trail, and repeat Only you can determine what your ideal trail bike looks like. That's why the Fuel is available in three customizable versions. The EX model offers versatility, while the MX loves jumps. And the LX will fly through anything with ease.
Adjustable damping curve Want to use the entire stroke while maintaining sensitivity to small bumps? Switching the chip on the lower shock mount gives you a more progressive lever ratio.
Integrated Zero Stack headset With the standard ZS headset, you have plenty of options for upgrades with replacement parts, including angle adjustment and anodized colors.
Storage space and accessory mounts All Fuel models, both carbon and aluminum, boast storage space in the frame where you can store all your essentials. Accessory mounts on the top tube allow you to carry even more.
New frame design The new Fuel frame offers plenty of space for long dropper posts, larger shocks, frame bags, and other accessories.
Active Braking Pivot The Active Braking Pivot system allows our engineers to tune the suspension to respond to acceleration and braking independently. The result is reliable handling.
A better way to make aluminum In 2024, we began replacing high-emission aluminum in our manufacturing with low-emission aluminum produced from renewable energy sources. Since October 2025, we have been producing almost all of our alloy wheels, including this model, using this new method, which has led to a significant reduction in our carbon footprint.
Shimano XT Di2 Looking for the latest speed-enhancing technology? The XT Di2 set offers lightness, lightning-fast shifting, and incredible reliability. Plus, it's wireless and allows for countless adjustments to suit your riding style.

TREK is headquartered in Waterloo, Wisconsin. The family-owned business was founded by Richard Burke in 1976, starting out in a small steel bicycle factory with just five employees. Within a few short years, the company caught on to bicycle trends and continued to grow. In the early 1990s, it began producing bicycles in a then-new material - Carbone. Today, TREK sets the trends in bicycle development and is also considered a leader in the processing of Carbone. Its proprietary processing technology, called OCLV, has been applied in production with many innovations for more than 17 years. TREK bikes have celebrated success at major world races and have been associated with names such as Lance Armstrong, Alberto Contador, Chris Lieto, Roland Green, Chris Eatough, Andrew Shandro and Travis Brown. TREK is a premium brand you can always rely on.
