Fuel EX 9.9 makes no compromises. Top-shelf suspension, carbon everything, and SRAM's latest X01 Eagle AXS wireless drivetrain make this ripper ready to rule any trail in style. It's fast, it's light, and it's got everything you need to crush your next trail ride.
It's right for you if...
You want a bike as versatile as you are, and you're demanding—of yourself and of your equipment. You want the lightest weight, the most adjustability, and the highest precision so the last thing you have to worry about on your next adventure is your bike.
The tech you get
A light and stiff OCLV Mountain Carbon frame with internal storage, FOX Factory suspension with Kashima Coat and an efficient yet plush RE:aktiv with Thru Shaft damper. A fully wireless SRAM X01 Eagle AXS 1x12 electronic drivetrain and RockShox Reverb AXS dropper post. Plus, Bontrager Line Carbon 30 wheels with a 108-tooth Rapid Drive rear hub for quick engagement, and a Bontrager Line Pro OCLV Carbon handlebar.
The final word
If you can have just one mountain bike, this is it. Fuel EX 9.9 has the lightest, most advanced parts with the most adjustability and precision. It's equally at home on fast flowy singletrack, brutal leg-busting climbs, and gnarly arm-pumping descents.
Why you'll love it
- The SRAM X01 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 Factory 36 fork gives you four-way damping adjustments, plus you get Kashima Coat for smoother, more durable stanchions
- 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 fully customizable through Project One
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
Will my bike have a curved top tube?
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
