Slash 9.8 GX | Trek Bikes

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 prioritize tunable suspension performance over a shiny top-shelf drivetrain.

A full OCLV Mountain Carbon frame with 160mm of travel and a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, plus a RockShox ZEB fork with extra-beefy 38mm stanchions. A SRAM GX Eagle drivetrain with a 10-52 cassette and Bontrager Line Elite 30 carbon 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 38mm 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 34.9mm 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

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.

Features

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

Watch the video

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 fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.

Complete Tubeless System

Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.

Oversized 34.9mm dropper post

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.

Carbon Care Wheel Loyalty Program

Every set of Bontrager carbon wheels is backed by the Carbon Care Wheel Loyalty Program. 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.

Threaded bottom bracket

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

Rapid Drive 108 rear hub

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.
