Overview

About this bike

Fuel EX 9.9 X0 AXS is a top-tier trail bike built for riders who have an appreciation for the finest things in life. It combines a cream of the crop carbon frame with top-tier components, from the carbon fiber wheels all the way up to the 150mm Kashima-coated FOX Factory fork, and rugged, fully wireless SRAM X0 transmission. It's a bike that rules the mountain and doesn't hesitate to lay claim to its domain, ripping up rock gardens, blasting berms, and rocketing back to the top to conquer it all once again. It's right for you if... You have refined taste in mountain bikes, and don't like to settle. You want a bike built to tackle the whole mountain and rule it all with the finest technology available, from its light and stiff carbon frame and wheels that track through the hairiest lines, to the FOX Factory fork and fully wireless SRAM X0 transmission. The tech you get A featherweight OCLV Mountain Carbon frame built to handle the rough and rowdy, a pair of finely laced carbon wheels that track through technical terrain with ease, and SRAM's top-tier X0 AXS direct-mount, fully wireless electronic transmission. Plus, you get the silky smooth travel of a 150mm FOX Factory 36 Fork with Float EVOL air spring and GRIP2 damper, 140mm of FOX Factory Float X rear suspension, and a RockShox Reverb AXS dropper post, all topped off with adjustable geometry for fine-tuning your ride to you and internal frame storage that lets you keep your setup tidy without leaving behind trail essentials. The final word Fuel EX 9.9 is a bike built to satisfy those with the finest taste. It pairs together an all- mountain trail capable carbon frame with the finest components you'll find on a modern mountain bike, from its carbon hoops to rugged, wireless SRAM X0 AXS shifting. It's all wrapped up with adjustable geometry, so you can fine tune your ride to always feel how you want it. Why you'll love it - Fuel EX Gen 6 gives you 140/150mm of travel with extra adjustability features and more stable handling, plus a more robust frame with internal storage - We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5" wheels, S frames get to choose between 27.5" or 29", and sizes M and up get 29" wheels - It's ready to rip with lightweight carbon wheels that easily tackle rough terrain and hold their line when things get rowdy - In-frame storage makes it easy to bring along all of your essentials, while keeping your setup streamlined and sleek - With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations Features: Internal Storage Internal frame storage makes it easy to ditch the pack and still carry your ride essentials. Active Braking Pivot Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most. Slack or steep, the choice is yours Install angle adjust headset cups (sold separately) to tweak the 64.5-degree head tube angle a degree steeper or slacker to your liking — all without impacting your bottom bracket height. Adjust the sus for full send Adjust leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don’t want to bottom-out, or when you want to run a coil shock. Transition to transmission SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner looking, it's also more precise under load, and easier to set up. Size-specific stays Size-specific chainstays provide balanced handling to keep the ride nimble for smaller riders and improve front wheel traction on climbs for taller riders. Business in the front, party in the back Craving the nimble ride of 27.5? wheels but don’t want to sacrifice the speed of a 29er? No need to choose. Fuel EX is mullet-ready, just throw Mino Link in high, toss on a 160mm fork, and get ready to party. BITS: Your trailside savior Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
