Top Fuel 8 NX | Trek Bikes (GB)

Overview

You’re looking for a do-it-all full suspension mountain bike that balances efficiency with shred-ability. You want to rip rough descents, fly up climbs and even do a couple XC races.

A lightweight aluminium frame, 120 mm RockShox Recon Gold RL fork with plush DebonAir spring, 115 mm of rear travel with a FOX Performance Float shock and a lighter SRAM NX Eagle drive train. Plus, hydraulic disc brakes, Bontrager DropLock dual remote suspension lockout and a Bontrager Line Dropper.

Top Fuel 8 gets you the value of an alloy frame with drive train, fork and brake upgrades that keep up as you progress in speed and skill.

This short-travel bike has a killer suspension set-up reminiscent of the all-mighty mullet – it's both efficient and ready to party
Bontrager DropLock's shifter-style lever lets you easily lock out both front and rear shocks at the same time for added sprinting or climbing efficiently. Plus, it controls your dropper post too
Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
You get a Straight Shot downtube for extra-stiff, responsive handling without added weight and a Knock Block headset that protects against spinning bars and fork crowns

"It's devilishly quick, accelerates in a way that makes it seem like my legs actually produce real power. It's stable, planted, and it tracks like it's supposed to. Endurance athletes will be able to remain seated over more terrain, saving precious energy over the long haul, while XC pinners will hook up better on steep technical climbs."

"The new Top Fuel might not be a pure XC-race bike anymore, but it's still precise and very fast. Its new trail orientation makes it a great choice for a rider who wants a fast and light bike with most of the the efficiency of a cross-country race bike, but with bit more versatility and playfulness."

"Top Fuel is damn efficient heading up, but when you hit a downhill the bike rides much more like a lightweight trail bike than a purebred XC race machine, and has no hesitation getting a little rowdy if you're willing to let it."

Features

Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

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.

Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.

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.

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.

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.

Control Freak cable management

The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
