MBUK’s Trail Bike of the Year 2022

“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.”

"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 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."

Will my bike have a curved top tube?

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.

Complete Tubeless System

Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.

Oversized 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.

Mino 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.
