Fuel EX 9.8 GX AXS Gen 5 - Trek Bikes (INE)

Overview

You want a single bike that can handle any trail with the light weight and vibration damping of a carbon frame. You're willing to pay for parts that give you a better connection with the trail, including crisp, precise wireless electronic shifting.

A light and stiff full-carbon frame with internal storage, FOX Performance 36 fork with a GRIP damper that offers more adjustment, and a RE:aktiv with Thru Shaft shock. SRAM's latest GX Eagle AXS wireless electronic drivetrain with a leg-saving 52-tooth climbing gear, plus all-new Bontrager carbon wheels with a 108-tooth Rapid Drive hub for instant engagement and powerful 4-piston brakes.

Fuel EX 9.8 is a great investment for one bike that does it all. You get a light carbon frame, but it's the parts that make this model, like the extra-adjustable GRIP damper, the magic-carpet ride of Thru Shaft and the blistering acceleration of carbon wheels with a Rapid Drive hub.

The SRAM GX Eagle AXS drivetrain is smart, smooth and completely wireless
RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
The Fox Performance 36 fork gives you four-way damping adjustments for extra-dialled suspension
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.

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

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.

RE:aktiv with Thru Shaft gives you unmatched grip and control with a shock that reacts to the terrain faster than anything else out there.

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.
