Rides XC. And the stuff that scares XC riders.

Top Fuel is a full suspension XC mountain bike that’s equally suited to racing and having an all-around great time on any trail. It’s fast, fun, and always up for an adventure.

Serious. Fun.

Whether you’re pinning a number on your jersey or hitting the jumps with your buds, Top Fuel delivers. It’s a contender in any XC race or marathon ride but knows how to cut loose when you’re hopping around in the woods.

More travel, more control

Every Top Fuel has a 120mm fork and 115mm of rear travel. It’s just right for speed when you’re putting the hammer down and fun when you’re railing corners and descents.

Laidback and stable

The updated XC geometry is longer, slacker, and more stable. Select models have a 13° stem, which you can run negative for a more progressive race posture or flip for a trail-friendlier fit.

Trail bike tech, race bike mentality

It shares design elements with Trek’s trail bike family, including a Straight Shot Down Tube for extra stiffness and Knock Block, which protects your frame from spinning bars and fork crowns.

Your ride, your way

Every Top Fuel has MinoLink adjustable geometry so you can fine-tune your fit, along with Control Freak cable routing so you can cleanly manage brake, shift, and dropper cables.

Ready to rip

Top Fuel is great for XC racing and off-the-beaten-singletrack adventures alike. Every model comes with a dropper post, and the frame has clearance for tires up to 2.4˝ wide.
