I picked up some S914s on Ebay. The claim is that they're on 17mm risers. As I look at them, there is no riser plate at all. Just a little plastic and metal to hold the mount screws to the skis. Last year I got some S912 ti bindings from backcountry.com. They showed up with risers almost a cm high, and with wide brakes even. I'm a complete alpine binding JONG. Did backcountry.com style me, or am I missing some parts with the Ebay purchase?
