It's right for you if...

You're a mountain biker through and through, and want a single carbon bike for the best performance on everything from XC races to gnarly descents and technical trail. You know you'll be riding this bike on every trail, so you're not going to compromise on frame material, suspension, or components.

The tech you get

A lightweight OCLV Mountain Carbon frame with full carbon stays, Bontrager Line Pro OCLV Carbon wheels with a 108-tooth Rapid Drive rear hub for instant engagement, SRAM's flagship XX1 Eagle 1x12 drivetrain, a 130mm FOX Factory Float fork, and 130mm rear travel with a FOX Factory Float rear shock featuring Trek's exclusive RE:aktiv with Thru Shaft. Plus, a Bontrager Drop Line dropper post, 35mm Bontrager Line Pro OCLV Carbon handlebar, and 35mm Bontrager Line Pro stem.

The final word

If you can have just one mountain bike, this is it. Fuel EX 9.9 has the highest-end parts on the best OCLV Mountain Carbon frame we make. It's equally at home on fast singletrack, gnarly trail, and everything inbetween.
