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 Tour. 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, a RockShox Lyrik Ultimate 160mm fork with a Charger 2 RC2 damper, and 150mm of rear travel with a RockShox Deluxe RT3 shock featuring Trek's exclusive RE:aktiv with Thru Shaft damper. Plus, a SRAM X01 Eagle 1x12 drivetrain, Bontrager Line Elite dropper post, Bontrager Line Pro carbon bars, and Bontrager 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?
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
- It's equally at home between the tape and in the rugged wild—Yes, Slash is a race bike, but it's ridiculously fun on gnarly trail rides, too
- Mino Link lets you adjust the geometry, so you get both an enduro race bike and an ultra-capable trail bike in one
- Control Freak Cable Management allows you to run any combination of cables exactly the way you want, while still giving you sleek looks and protecting your cables against unnecessary wear
Features
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.
Trek's Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
RE:aktiv with Thru Shaft gives you unmatched grip and control with a shock that reacts to the terrain faster than anything else out there.
