Product Details

2019 Trek Fuel EX 9.9 29

Fuel EX 9.9 is our best 130mm trail bike. A carbon frame, carbon wheels, a 1x12 SRAM X01 Eagle drivetrain, and FOX Factory Float suspension make this the one carbon full suspension mountain bike that rules every trail. It's fast on XC singletrack, light on climbs, and stable through the rowdiest terrain you can find.

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 Carbon wheels with a 54-tooth Rapid Drive rear hub for instant engagement, a 1x12 SRAM X01 Eagle drivetrain with a carbon crank, a 130mm FOX Factory Float fork, and 130mm rear travel with a FOX Factory rear shock featuring Trek's exclusive RE:aktiv with Thru Shaft. Plus, a Bontrager Line dropper post, 35mm 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 high-end parts on the best OCLV Mountain Carbon frame we make. It's equally at home on fast singletrack, gnarly trail, and everything in-between.

Why you'll love it

1 - Fuel EX 9.9 is the single best choice for riders who want a versatile ripper for every kind of mountain biking, from fast XC races to burly technical terrain
2 - RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
