Spark R&D now developed, on popular demand, a Heel Lock for the Tesla series. Also brandnew is the DYNO DH, a special binding for Hardboot riders. Uphill you'll use the normal Dynafit adapters, compatible boots assumed. The suitable D-Rex crampons fit into the standard Dynafit mounts.
See our presentation video for pictures and the available new colors for the Afterburner and Magneto bindings, too.
