Product Info

The Spark R&D Surge ST binding is trusted by professional big line riders and mountain town legends alike. It’s a powerful binding with a more robust ankle strap and stiff highback, perfect for big days and big lines. The new ST Touring Bracket and ST Whammy Bars make this binding even more efficient while touring to the steeps. The new ST (Smooth Touring) series from Spark R&D is the same gear you know and love with subtle but important upgrades. Some previous model componentry is not cross compatible.

Tesla T1 Chasis – CNC machined baseplates remain solid for max stiffness and durability. All of the baseplate side windows have been partially filled to increase durability and strength.
