MBUK’s Trail Bike of the Year 2022
“It’s easy to look at the bike from afar and assume this is just another down-country rig... It wasn’t until I’d fired it over some jumps, nosed it down the odd steep chute and slung it through my test loops’ berms that I realised the Top Fuel is, simply put, a bloody brilliant trail bike.”

"Enduro’s Best Downcountry Bike of 2022"
"The Top Fuel 9.9 XX1 AXS earned top honours in Enduro’s round-up of best off-road rippers, thanks to the bike’s clean look, practical details and progressive suspension."

"This is a really, really good bike"
"The Top Fuel is a very capable descender, but its well-proportioned geometry is just half the story. It manages to strike a great balance between grip, tracking and precision. The whole bike seems to just will you on to hit things faster and with more precision."

"This thing rips"
"The new Top Fuel is also much more composed on rough and fast descents. Thanks to the longer reach and slacker head angle, the overall wheelbase length has grown by almost 40 mm. That’s huge, and it offers a vastly more planted feel at speed. Along with the big tyres and active suspension, this really is a solid little trail bike."

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.
Quick and in control
120 mm of rear travel combined with progressive trail geometry gives you a fast, responsive ride that helps you keep your cool when the trail turns rowdy.
Internal Storage
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Hassle-free routing
Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.
Will my bike have a curved top tube?
The smaller frames (XS and S) have a curved top tube. This design makes for a lower standover height, which allows shorter riders to straddle the bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.
Complete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Learn moreOversized 34.9mm dropper post
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
Threaded bottom bracket
More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.
ISCG mounts
International Standard Chain-Guide mounts offer easy chain-guide installation and adjustment.
Knock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
Learn moreMino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
