          More Give. More Go.

          Featuring Kingpin, a revolutionary, super-light suspension that lets you ride harder on dirt and more smoothly on pavement. Better control. Better traction. Better comfort. Nothing sacrificed.

          It’s easier to go harder

          More Info

          Refined geometry and rider position deliver an experience that’s stable, composed and comfortable without losing that spark. Go further, ride longer, charge harder.

          Load and go

          More Info

          Plenty of places to store gear and water, with a multi-position mount on the downtube, and more on the top tube, seat tube, and under the down tube. There's even mounts on the forks.
