    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 wireless electronic 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 low weight and vibration damping of a carbon frame. You’re willing to pay for parts that give you a better connection with the trail, including crisp, precise wireless electronic shifting.

    The tech you get
    A light and stiff full-carbon frame with internal storage, FOX Performance 36 fork with a GRIP damper that offers more adjustment, and a RE:aktiv with Thru Shaft shock. SRAM’s latest GX Eagle AXS wireless electronic drivetrain with a leg-saving 52-tooth climbing gear, plus all-new Bontrager carbon wheels with a 108-tooth Rapid Drive hub for instant engagement, and powerful 4-piston brakes.

    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
    – The SRAM GX Eagle AXS drivetrain is smart, smooth, and completely wireless
    – RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
    – The Fox Performance 36 fork gives you four-way damping adjustments for extra-dialed suspension
    – 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
    – Make it yours: it’s customizable through Project One
