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 a SRAM wireless electronic drivetrain and dropper make this top-of-the-line ride the undisputed king of enduro.

It's right for you if...

You're looking for the kind of enduro bike that can rip it up on the world’s biggest stage. You like going fast, getting rowdy and railing corners, and you want top-shelf electronic components that can keep up.

The tech you get

A full OCLV Mountain Carbon frame with 160 mm of travel and a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a RockShox ZEB Ultimate fork with extra-beefy 38 mm stanchions. A wireless electronic SRAM X01 Eagle AXS drivetrain with a 10-52 cassette, Reverb AXS dropper, Bontrager RSL integrated bar/stem, and Line Pro 30 carbon wheels with a 108-tooth Rapid Drive hub.

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 that this bike is fast?

Why you'll love it

1. 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
2. The OCLV Carbon RSL integrated bar/stem is ultra-light and ultra-comfortable, and it looks awesome
3. We added a second down tube guard to better protect your frame from shuttle-related damage
4. Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster
5. A large internal storage compartment in the down tube lets you stow tools and gear
