Incredibly flexible and with a medium light weight, the Flux RK Snowboard Binding provides that loose, surfy feeling for those who want to skate the whole mountain. Speaking of skating, Flux took inspiration from skateboarding to pioneer the use of soft, smooth flexing urethane in the highback. The RK takes this idea to the next level with its Solid Urethane highback. Designed with a super soft torsional flex, the Solid Urethane highback elevates your park and freestyle progression, helping you bone out grabs and lock into presses without excess stiffness inhibiting your movement. Reinforcing the center to prevent the highback from folding over, a solid spine keeps things slightly stiffer for landing support and a bit more heelside response. Dialing in a comfortable fit, the binding's F Tech 3D Fit ankle strap conforms to any boot on the market, eliminating pressure points with its 3D molded shape. Flux re designed the FTM Versa toe strap to accommodate over the tip and over the top wear, should you opt to wear your toe strap in a traditional fashion. The urethane mounting four hole disc Channel disc available through Flux flexes underfoot, maximizing the flex of your freestyle board by eliminating the dead spot inherent to solid mounting discs.
