Trek Fuel EX 9.8 GX Gen 5 – Carbon Trail Bike Performance Without Compromise

Take your trail riding to the next level with the Trek Fuel EX 9.8 GX Gen 5 – a high-performance, full-carbon mountain bike engineered for riders who crave versatility, precision, and control. Whether you're tackling technical climbs, fast flowy descents, or all-day epics, this trail bike is built to push boundaries and redefine your off-road experience.

Why Choose the Fuel EX 9.8 GX Gen 5?

  • Full OCLV Mountain Carbon frame for exceptional strength-to-weight ratio and vibration damping
  • FOX Performance suspension – 130 mm rear & 140 mm front travel with upgraded GRIP damper for enhanced small bump sensitivity
  • SRAM GX Eagle 12-speed drivetrain with massive 10-52T range – perfect for conquering steep ascents
  • Carbon wheels with Bontrager Rapid Drive rear hub – fast engagement for punchy acceleration
  • RE:aktiv with Thru Shaft rear shock – delivers superior traction and faster response than traditional dampers
  • Internal frame storage – stash your tools or gear inside the downtube for hassle-free adventure readiness

Built for Riders Who Demand More

The Fuel EX 9.8 GX Gen 5 isn't just about premium materials – it's about smart design that translates into real-world trail dominance. Its Straight Shot frame design with Knock Block boosts frame stiffness without compromising handling. And with Active Braking Pivot (ABP), the rear suspension stays active under braking, giving you confident control over roots, rocks, and rowdy descents.


Tailor-Made for the Trail

From aggressive downhills to tight switchbacks, the Fox Performance 36 fork with 4-way adjustability allows you to fine-tune your ride to the terrain. The wide 780 mm carbon handlebar and dropper post add confidence, while tubeless-ready wheels and high-traction Bontrager XR4 Team Issue tyres offer grip you can trust, no matter the conditions.


Who’s This Bike For?

The Fuel EX 9.8 GX Gen 5 is perfect for riders who:

  • Want a high-performance carbon trail bike without the sky-high price of flagship components
  • Love riding varied terrain, from technical singletrack to alpine loops
  • Value responsive handling, excellent suspension, and integrated features like internal storage and cable routing

Redefine Your Ride

With its perfect blend of capability, innovation, and all-out fun, the 2021 Trek Fuel EX 9.8 GX Gen 5 is more than a trail bike—it’s your ticket to exploring more, climbing higher, and descending harder. Don’t settle. Ride faster, ride further, and ride Fuel EX.
