Fuel EX 5 Gen 5 - Trek Bikes (IN)

Overview

You're ready to go full suspension, and you want a versatile trail bike at a great value. You want a ride that's sure-footed, capable and responsive, so you can stay in control no matter where you're riding.

A sturdy aluminium frame with a Knock Block steerer stop to protect against spinning bars. A 140 mm RockShox Recon Silver fork, 130 mm of rear travel with an X-Fusion Pro 2 shock, a durable 12-speed Shimano Deore drivetrain, dropper post and hydraulic disc brakes.

You get full suspension performance without the sticker shock. The Fuel EX 5 has the same proven frame technology that riders have loved over the years, with parts chosen to keep the price tag low and stoke level high.

You get a high-end ride at an exceptional value with frame features like Boost148 and ABP that give you confident handling and room to upgrade parts as your skills grow
It has the capability of far more expensive trail bikes: it shreds singletrack and can even handle the occasional XC or enduro race
The dropper post lets you lower your saddle on the fly so it's out of the way on descents
The RockShox fork's DebonAir spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝ and sizes M to XL get 29˝ wheels

'The Fuel EX is a beautifully balanced and capable trail bike. The rear suspension is beautiful; as close to ideal as any bike I've ridden. It's sensitive where you want it to be, firm and crisp where it should be. It feels deep and controls big hits very well, and there's a nice platform for pedalling, and to pump and pop off when you're playing.'

'The Fuel EX has a few tricks that help it keep a level head when outside of its comfort zone, and to be a cloud on rails when it's in the zone. Everything about the Fuel EX, which was already good at pleasing everybody, is now even better.'

'Thanks to its burlier components, increased travel and more aggressive geometry, it has become more of a shredder than ever! More performance, fun and trail prowess.'

‘In a world where most new full-suspension mountain bikes are amazing, Fuel EX stands apart as even more than that.’

Choose from the lighter 130/140 mm Fuel EX Gen 5 with better parts for the price or the more robust 140/150 mm Fuel EX Gen 6 with more adjustability.

Features

Smaller frames (XS and 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. 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.

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.

Trek's Straight Shot frame design optimises the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.

Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff and the fun. With smooth riding, improved chain stability and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.

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.

Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.

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.

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
