The Surge ST Pro Splitboard Bindings swap the standard Surge's glass-reinforced highback for a carbon-reinforced nylon version, built through injection molding for more complex geometry and stronger impact resistance without adding stiffness where it isn't needed. Custom aluminum hardware replaces seven stainless steel components for a 65% weight cut, so the binding holds its edge on steep, technical terrain without carrying extra grams up the skin track. What Our Gearhead(R) Experts Are Saying:"I dropped into a line steeper than anything I'd normally split for, and the highback held its shape through every hard edge set without any flex creeping in. Getting there felt lighter too, my legs weren't fighting the gear on the way up like they usually do in a stiffer binding."
