Overview
About this bike
Slash 9.8 is a carbon enduro mountain bike built to handle big hits, rail corners, and rip down the mountain faster than you ever thought possible. Ultra stiff and ultra tough carbon frame, carbon wheels, and the most refined suspension tech from RockShox make this long-travel 29er a worthy contender for any dedicated rider and enduro podium. It's right for you if... You're looking to tackle huge days on huge mountains, whether it's an enduro race or an epic adventure. You want the light weight and muted vibes of a carbon frame, and you prioritize tunable suspension performance over a shiny top-shelf drivetrain. 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 Thru Shaft damper, plus an all-new RockShox ZEB fork with extra-beefy 38mm stanchions. A Shimano XT 12-speed drivetrain for super-smooth shifting that's easy on the thumb and Line Elite 30 carbon wheels with a 108-tooth Rapid Drive hub for quick acceleration when you need it most. The final word This is a beast of a mountain bike. You get hot new suspension technology normally reserved for the most expensive bikes, and you get it on a fresh new frame. With Slash 9.8, the faster you go, the better it rides, so giddy-up. Why you'll love it - 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 - 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 34.9mm diameter post is stronger, more durable, and moves up and down faster
