“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 moreActive 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.
Designed to meet the highest level of competitive mountain bike racing needs, with second to none performance and experience, Shimano XTR M9100 brings lightweight, high-end versatility to XC, enduro, and marathon racing.

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.
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.
