Slash 9.9 is the fastest enduro mountain bike in the line-up, so it's no surprise it's the go-to ride for the pros of Trek Factory Racing Enduro. A full carbon frame, all-new hard-charging suspension, fast-rolling carbon wheels and SRAM's newest X01 Eagle drive train make this top-of-the-line ride the undisputed king of enduro.

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.

A full OCLV Mountain Carbon frame with 160 mm 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 38 mm stanchions. A SRAM X01 Eagle drive train 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.

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 that this bike is fast?
- 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
- 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 34.9 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

Internal Storage
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
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.

OCLV Mountain Carbon
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.
