The S18 Source Forged Carbon highback and integrated 3-stage FLAD system provide precise control across all terrain types.
This premium binding puts you directly in the driver's seat with its innovative design that removes excess material without sacrificing performance, making it ideal for advanced riders seeking the ultimate in lightweight precision and power transfer.
