Fuel EX 9.8 combines a light full-carbon frame with parts chosen for the highest performance-to-price ratio. High-end FOX suspension with upgraded front and rear dampers, carbon wheels with a Rapid Drive rear hub, and SRAM's latest, widest-range drivetrain give this model an extra edge you'll notice from the first pedal stroke.
It's right for you if...
You want a single bike that can handle any trail with the light weight and vibration damping of a carbon frame. You're willing to pay for parts that give you a better connection with the trail, but you'd rather skip the bling.
The tech you get
A light and stiff full-carbon frame with internal storage, FOX Performance 36 fork with wider stanchions for more stiffness on rough terrain, and a RE:aktiv with Thru Shaft shock. SRAM GX Eagle drivetrain (Cable or AXS) with a leg-saving 52-tooth climbing gear OR a Shimano XT 1x12 drivetrain for super-smooth shifting that's easy on the thumb with an extra-low 51-tooth climbing gear, plus Bontrager carbon wheels with a 108-tooth Rapid Drive hub for instant engagement.
The final word
Fuel EX 9.8 is a great investment for one bike that does it all. You get a light carbon frame, but it's the parts that make this model, like the extra-adjustable GRIP damper, the magic-carpet ride of Thru Shaft, and the blistering acceleration of carbon wheels with a Rapid Drive hub.
Why you'll love it
- Fuel EX 9.8 will take your riding to the next level with a parts package that gives you top-shelf performance without the top-shelf price tag
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- A sleek internal storage compartment gives you a handy spot to stow flat fixing supplies or gear
- 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
