It's right for you if...
You're looking for the kind of performance advantages that come only from the kind of enduro race bikes that rip it up on the world’s biggest stage. You like going fast, getting rowdy, and railing corners all the way to the top step of the podium.
The tech you get
A full OCLV Mountain Carbon frame with 160mm 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 38mm stanchions. A SRAM X01 Eagle drivetrain with the new 10-52 cassette and Line Carbon 30 wheels with a 54-tooth Rapid Drive hub for quick acceleration when you need it most.
The final word
There's not a single part on this bike that wasn't made for ripping it up at insane speeds on the wildest enduro courses in the world. Fast, tough, fast, fun, fast. Did we mention this bike is fast?
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

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

Enduro Bike of the Year
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.

"A hell of a bike"
"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."

Features
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
RockShox Super Deluxe Thru Shaft damper
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.
Complete frame protection
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

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
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.

Sizing & Tech
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.
