Trek Slash 9.9 XTR - 2021

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, fast-rolling carbon wheels, and Shimano's newest XTR drivetrain 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 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.

The tech you get
A full OCLV Mountain Carbon frame with 160mm of travel and an all-new RockShox Super Deluxe Ultimate shock with an updated ThruShaft damper, plus an all-new RockShox ZEB fork with extra-beefy 38mm stanchions. A Shimano XTR drivetrain for refined, super-smooth shifts, and fast-rolling Line Pro 30 OCLV Mountain Carbon wheels. The large internal storage compartment in the down tube lets you stow tools and gear.

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?
