Quick overview

The Spark R&D Surge ST Pro has undergone some changes. In addition to being very light (+/- 140 grams lighter than the Surge), the Surge Pro is also a lot stiffer and more responsive. This saving and change in flex is mainly achieved by replacing the hardware, carbon in the highbacks and Pebax platic in the straps. ST stands for 'smooth touring' where friction and wear are eliminated. The whammy bar (heel riser) is connected to the binding and ensures that the crampons always fully engage. The addition of the skipole adjustable heel riser makes this one of the most practical bindings in the field. This binding is the stiffest in the Spark line and therefore suitable for the bigger riders or big chargers who spend long days out in the backcountry.



The Spark R&D Surge ST Pro is a real weight watcher. The Carbon Reinforced Asym Rip N' Flip Highback is stiffer and lighter than the normal version. All hardware and the heel loops have been replaced by the ultra-light 7075 Aluminum. These parts are therefore no less than 65% lighter than the metal version. The character of the Surge ST Pro resembles that of the Surge ST, but the flexibility has decreased. The light weight properties are mainly in the milled CNC baseplate, stripped of all unused material. The chassis sidewalls have been partially filled to enhance durability and strength. The bindings are equipped with Smooth Touring (ST) touring brackets, these brackets are made of a mix of aluminum and thermoplastics, which reduces friction and thus increases the lifespan.

The Arc ST Pro and the Surge ST Pro are both equipped with the Full Pebax Plastic Pillow Line Straps. These straps are lighter, thinner and more resistant to cold than the normal Pillow Line straps. The straps are 3D-shaped from a single piece of plastic. This gives them a good lifespan and better deformability, so that they fit optimally on your boot. The ST Whammy Bar heel riser is built into the baseplate and ensures that the crampons, regardless of the heel riser, fully engage. The Whammy Bar has an ST overmold. During the overmold process, plastic is poured over the metal parts to make it stronger and more durable. Spark R&D uses time-tested Burton Buckles in all of their closures.

The Spark R&D Surge ST Pro uses the well-known Tesla T1 system. This system works with a heel riser in the baseplate and the Snap Ramp click system for converting interface. This makes it easy to mount the binding on Voile and Spark pucks.
