“It’s easy to look at the bike from afar and assume this is just another downcountry 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.”Read more
"Top Fuel 9.9 XX1 AXS earned top honors in Enduro’s round-up of best downcountry rippers, thanks to the bike’s clean look, practical details, and progressive suspension."Read more
"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."Read more
"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 40mm. 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."Read more

Everything you need (and nothing you don’t).Learn how
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.
120mm 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 frame storage makes it easy to ditch the pack and still carry your ride essentials.
Guided internal cable routing keeps Top Fuel quiet on the trail and maintenance a breeze.
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
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. 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.
This bike doesn’t come with pedals because you'll have a better ride if you choose your own. Explore the pedal guide to find the best pedals for your riding style. Reach for flat pedals for simple versatility or go for clipless MTB pedals if you want control & efficiency.
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.
International Standard Chain Guide mounts offer easy chain guide installation and adjustment.
More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.
