Trek updates Top Fuel with longer travel and new geometry!

Trek announced a redesign of its popular full suspension cross country bike today, updating Top Fuel with longer travel and an all-new geometry that’s suited to racing and a whole lot more.

Top Fuel has long been the bike of choice for speed and efficiency on demanding cross-country courses and marathon rides. The new models combine Top Fuel’s race heritage with the confident control of a longer-travel bike for a ride that handles like a snappy XC race bike and rips like a trail bike.

This change in design pivots Top Fuel from a thoroughbred race machine to a cross country bike that’s well-suited to both racing and an all-around great time on any trail for any rider.

Earlier this spring, US Marathon Mountain Bike National Champion Payson McElveen (Orange Seal Off-road) rode the new Top Fuel to a record FKT on the 100-mile White Rim Trail in Utah’s Canyonlands National Park, beating the previous record by nearly 15 minutes.

More travel, more control

Whereas previous Top Fuel models featured a 100mm fork and 100mm of rear travel, the new Top Fuel models have a longer 120mm fork and 115mm of rear travel.

New Top Fuel models also feature an overhauled frame with a slacker head angle and a longer reach for confidence and control on rough descents.

Each of the models in the new Top Fuel lineup features a wider handlebar and shorter stem, a dropper post, and a TwistLoc dual remote lockout that makes it easy to simultaneously lock the front and rear suspension for sprints and climbs.

Trail bike tech, race bike mentality

The new Top Fuel frame has similar design elements to Trek’s trail bikes, including a Straight Shot down tube for extra stiffness without extra weight and Knock Block frame defense that prevents damage from spinning bars and fork crowns.

Each new model features Mino Link adjustable geometry, Control Freak internal cable routing, and Active Braking Pivot, which keeps the suspension active even when you’re on the brakes.

Together, this frame and suspension tech makes for an ultra-responsive and sure-footed ride that’s fast on race day and fun whenever you ride.

Any Questions?!

When will new Top Fuel be available in Project One?

New Top Fuel will be available in Project One late July.

There’s no Mino Link on the seatstay. Where’s Mino Link?

Top Fuel still features Mino Link adjustable geometry, but now it’s integrated into the upper shock mounting bolt, and it’s easier to use.

In which Mino Link position does the bike ship?

All Top Fuels will ship in the Low Mino position, ready to get rowdy. That leaves the option to go taller/steeper for those riders who want quicker steering.

What is the max fork travel?

130mm

What is the max rotor size?

180mm front and rear.

What is the max chainring size?

34-tooth.

Is it compatible with aftermarket shocks? Which ones?

We’ve tested and can recommend Fox Float LV and RockShox Deluxe shocks.

Is it compatible with cranks with 30mm spindles?

Yes.

Are there ISCG mounts? Can I run a chain guide?

There are no ISCG mounts because Top Fuel is still a weight-conscious XC bike, and ISCG tabs make the frame heavier. We will offer an aftermarket chain guide that clamps to the BB shell for riders who want additional chain retention security.

Is it compatible with 2x drivetrains?

No.

What is the max tire size?

29×2.4”

Is it compatible with 27.5” or 27.5+ wheels and tires?

No.

Why does the size Small have 29-inch wheels? What happened to Smart Wheel Size?

We still believe Smart Wheel Size makes sense for most cross country hardtail riders where seated pedaling takes priority. Smaller 27.5” wheels allow shorter riders to easily achieve an efficient position on the bike for producing power.

New Top Fuel is as much about capability as it is speed. These riders stand up and move around on the bike a lot more, so it uses 29-inch wheels on all sizes. This makes it easier for shorter riders to roll over bigger trail obstacles faster.
