It's right for you if...
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.
The tech you get
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.
The final word
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 Walkthrough
favorite_borderWhy you'll love it
- 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

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.

Knock Block
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.
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.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
