A SRAM X01 Eagle drive train with the new 10-52 cassette and Line Carbon 30 wheels with a 54-tooth Rapid Drive hub for quick acceleration when you need it most.
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?
Why you'll love it
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
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 34.9 mm diameter post is stronger, more durable, and moves up and down faster
A large internal storage compartment in the down tube lets you stow tools and gear
