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 OCLV Mountain Carbon frame, RockShox Lyrik Ultimate fork, Trek's exclusive RE:aktiv with Thru Shaft shock, fast-rolling carbon 29er wheels and a Shimano XTR drivetrain and 4-piston brakes 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 Tour. You like going fast, getting rowdy and railing corners all the way to the top step of the podium.
