The connection between rider and snowboard has never been closer. We removed the mounting disk, reduced the baseplate height, and cut hundreds of grams of excess weight. The result completely changes how your energy transfers from body to board. The Union Source FC puts you in the driver’s seat. Are you ready for the ride?
