Top Fuel 7 | Trek Bikes (GB)

Overview

You want a full-suspension mountain bike that’s fast on flats and rolling terrain, but has enough travel to get wild on the trail. You want a solid build spec at a price that won't break your bike bank.

A lightweight aluminium frame with internal storage, 120 mm RockShox 35 Gold fork, 120 mm of rear travel with FOX Performance Float DPS shock with a 3-position damper and a wide-range Shimano Deore/XT drivetrain. Plus, Bontrager Line Comp 30 wheels that are already completely tubeless-ready, including sealant, hydraulic disc brakes and a dropper post.

Top Fuel 7 is an awesome and affordable bike that's a blast to whip around on and easier on the wallet. It's fast and fun and perfect for riders who want to test their mettle on all types of trails.

This bike’s killer suspension set-up is both efficient and ready to party
Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
A sleek internal storage compartment gives you a versatile spot to stow tools and gear
New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius

“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.”

"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."

"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."

"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."

Features

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.

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 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.

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.

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.

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.

This suspension calculator will help you optimise your suspension settings for your riding weight. Simply follow the steps to find your best set up.

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.

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.
