Slash 9.9 is the fastest enduro mountain bike in the lineup, 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 with RockShox Flight Attendant, fast-rolling carbon wheels, and a SRAM wireless electronic drivetrain and dropper make this top-of-the-line ride the undisputed king of enduro.

The tech you get

A full OCLV Mountain Carbon frame with 160mm of travel and a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a RockShox ZEB Ultimate fork with extra-beefy 38mm stanchions. Plus, RockShox Flight Attendant wireless electronic damping control automagically adjusts your suspension to best suit the terrain. 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.

Why you'll love it

1. The RockShox ZEB fork's bigger 38mm 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 ultralight, ultra-comfortable, and it looks awesome
3. RockShox Flight Attendant uses wireless sensors in the fork, shock, and crank to automatically adjust your suspension damping to the terrain. It's one less distraction from the trail ahead
4. Wider seat tube, wider dropper—the 34.9mm 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
