It's right for you if...
You're a big-mountain rider with your eyes on the Enduro World Series, so you're looking for every performance advantage you can get in a frameset. You ride sketchy descents at scary speed, and you want a bike that can keep up with your all-mountain aspirations.
The tech you get
A trail-tough OCLV Mountain Carbon frame with Control Freak internal routing, 160mm of travel with a RockShox Super Deluxe Ultimate shock with plush DebonAir spring and updated Thru Shaft damper, a 35mm Bontrager Line Pro stem, and an integrated Knock Block 2.0 headset that stops spinning bars and the fork crown from hitting your frame. Built for 29er wheels and a 170mm or 180mm fork.
The final word
This is the same frameset raced by the pros of Trek Factory Racing Enduro. It's tough, fast, responsive, and fully capable of taking on the wildest enduro courses in the world.
The Walkthrough
favorite_borderWhy you'll love it
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- A large internal storage compartment in the down tube lets you stow tools and gear
- Mino Link lets you adjust the geometry, so you get both an enduro race bike and an ultra-capable trail bike in one
- 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
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.

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.

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.

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.
