The Walkthrough
favorite_borderWhy you'll love it
- 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
- The OCLV Carbon RSL integrated bar/stem is ultra-light and ultra-comfortable, and it looks awesome
- 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
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.

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

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 Programme
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
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.
SRAM Eagle AXS drivetrain
Enjoy precise, lightning fast gear changes – even when shifting under load – with Eagle AXS wireless electronic drivetrains. They're water and dust-proof, and the AXS app makes it easy to personalise your settings.
