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 160 mm 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 38 mm 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 that this bike is fast?

The Walkthrough

favorite_borderWhy 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. Shimano XTR delivers smooth, precise shifting with just a light touch of the lever
  3. New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
  4. We added a second down tube guard to better protect your frame from shuttle-related damage
  5. Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster


RockShox Super Deluxe Thru Shaft damper

With the all-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most refined shock on the market, with an updated air spring and an exclusive Thru Shaft damper that gives you tenacious grip, plush control and the support you need for ripping rough descents all day.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
