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.
