Den har en rampvinkel.."As we mentioned in our dissection, here are the specs.Size ?N? (large?) Guardian, binding weight of 1480 grams (52.3 ounces) per binding with all hardware. Stack height (boot above ski at heel) is 27 mm at the toe and 32 mm at heel (verified at WildSnow HQ on demo board). Compare to main competitor at 37 and +-37 (latter due to for/aft height adjustable AFD on competition). Thus, you get around 5 mm less stack with the Salomon, but you do get some binding delta (drop at the toe) while the competition has a virtually neutral delta."
