K2 beefed up the design of its successful Company binding with the 2013 Company IPO. The IPO includes the Tweakback Highback made from a pliable urethane and designed for maximum freestyle flexibility. Tweakback Highbacks are stable and supportive when engaged yet loose and bendy when riders get grabby. The binding’s Pro-Fection Chassis are designed for strength, consistent flex and optimal rider response while the canted Harshmellow Basepad prevents chatter and absorbs impacts. Finally, the binding’s new RADchet aluminum ratchet levers feature a lightweight, one-arm design for smooth operations and durability.
