Spark R&D Dyno DH Binding – Hardboot Precision for Fast, Powerful Descents The Spark R&D Dyno DH Binding is the gold standard for hardboot splitboarders who want ultralight efficiency uphill and locked-in power on the way down. Tour on tech toes for the climb, then slide the Dyno DH onto your pucks and snap in for responsive, hard-charging ride mode. Purpose-built for hardboots, the Dyno DH pairs stainless toe/heel bails and a reinforced baseplate with an updated toe clip that grips low-profile AT boot soles securely. The result is a rigid, confidence-inspiring interface that keeps weight down and control high on steep, technical lines. Ride Mode Only—Optimized for Hardboot Setups Carry the Dyno DH in your pack for the approach, use your tech toe pieces to skin efficiently, and swap to the Dynos at the top for the descent. The Snap Ramp locks cleanly onto Spark Pucks (Canted Pucks recommended) for a fast, frustration-free transition.
