Details: Surge ST Pro splitboard bindings feature all the same great assets as our standard Surge ST bindings - T1 technology, Tesla snap ramps, solid baseplates, stiff highbacks, responsive Pillow Line Straps - but they are tuned up with premium materials and custom versions. We used carbon reinforced nylon in the highbacks, full Pebax plastics for the straps, ladders and adjusters, 7075 aluminum in the heel loops allowing us to make them thinner and lighter, 7 custom made screws and hardware pieces, and lastly, we hollowed out the steel pivot pins to shave a few more grams.
