It's right for you if...

You want a do-it-all mountain bike that’s second to none. You care about it all – from a pristine carbon frame and wheels to the lightest and best drivetrain from Shimano, and you don't want to sacrifice suspension performance for anything. You have good taste, and you know it.

The tech you get

A light and stiff OCLV Mountain Carbon frame with a 150 mm FOX Factory 36 fork with EVOL air spring and GRIP2 damper and FOX Factory Float X rear shock with 2-position damper that makes light work of the gnarliest rock gardens on the mountain. Carbon wheels that keep weight down while offering stiff and reliable tracking through rowdy terrain, and Shimano's finest drivetrain with the lightweight, reliable and precise XTR component package. Plus, you'll get adjustable geometry for fine-tuning your ride and in-frame storage that lets you keep your set-up tidy without leaving behind trail essentials.

The final word

The Fuel EX 9.9 is a top-tier trail bike that's built for riders with an affinity for the finer things in life. It's a complete package, with the industry's best components from the ground up, with Shimano's XTR drivetrain, FOX Factory fork, carbon wheels and frame, and geometry that's ready to be tuned for how you ride.
