Slash 9.8 GX - Trek Bikes (IE)

Overview

You're looking to tackle huge days on huge mountains, whether it's an enduro race or an epic adventure. You want the light weight and muted vibes of a carbon frame, and you prioritise tunable suspension performance over a shiny top-shelf drive train.

A full OCLV Mountain Carbon frame with 160 mm of travel and an all-new RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, plus an all-new RockShox ZEB fork with extra-beefy 38 mm stanchions. A SRAM GX Eagle drive train with the new 10-52 cassette and Line Carbon 30 wheels with a 108-tooth Rapid Drive hub for quick acceleration when you need it most.

This is a beast of a mountain bike. You get hot new suspension technology normally reserved for the most expensive bikes, and you get it on a fresh new frame. With Slash 9.8, the faster you go, the better it rides, so giddy-up.

The RockShox ZEB fork's bigger 38 mm stanchions help you stay on your line through the chunky stuff, while the updated damper lets you dial in the feel
New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
We added a second down tube guard to better protect your frame from shuttle-related damage
Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster
A large internal storage compartment in the down tube lets you stow tools and gear

'The combination of high-end performance with individuality and user-friendliness in the thought-through package delighted the entire jury.'

‘The Slash has a big-bike feel that makes it easier to charge into an unfamiliar trail, while retaining enough manoeuvrability to prevent it from feeling like overkill on mellower trails.’

Once the dust had settled, it was the Slash that managed to edge its way into the lead. Its ability to tackle the wildest terrain without flinching yet all the while retaining that reactive, lively feel really won us over.

‘Slash is great on rough, bermed corners and it has been an absolute monster riding steeps. This is an easy bike to ride and everything felt very natural from the first drop in and I haven’t looked back since.’

Transitions? Tech zones? Walking?! It's Enduro 101 and Pinkbike's Christina Chappetta is here to break down everything you need to know before you line up between the tape.

Features

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

With the all-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most refined shock on the market, with an updated air spring and an exclusive Thru Shaft damper that gives you tenacious grip, plush control and the support you need for ripping rough descents all day.

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.

Replaceable down tube guards protect the underside of your frame from rock strikes, trail debris and janky shuttle vehicles so you can forget about damage worries and focus on blasting the next run.

Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.

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.

Every set of Bontrager carbon wheels is backed by the Carbon Care Wheel Loyalty Programme. In the unlikely event that you damage your Bontrager carbon wheels within the first two years of ownership, we’ll repair or replace them for free.

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.

Slash is built for the hardest riding in the harshest conditions with a threaded bottom bracket that's more robust than press fit.

With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
