It's right for you if...
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.
The tech you get
A lightweight 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.
The final word
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.
favorite_borderWhy you'll love it
- 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
'A world-class trail bike!'
'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.'Read more
Will my bike have a curved top tube?
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.
Alpha Platinum Aluminium
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.
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.
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.
