Trek fuel ex 9.9 xx1 axs gen 6

• You care about the finer things in life, like silky-smooth suspension that feels greater than the sum of its numbers, and fully wireless shifting that keep your setup tidy and low maintenance
• You can tackle any trail on the mountain with its progressive geometry that makes light work of steep, punchy climbs, and turns around to rally the descents
• It comes with light and stiff carbon wheels that make quick work of technical terrain and keep you on your line, even when things get hairy
• 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
• With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations

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 youre hitting big features and don’t want to bottom-out, or when you want to run a coil shock.

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.
