Plus, Bluetooth connectivity makes it easy to add a display if you want to make it easier to see your ride data.

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.
