The Spark R&D Surge is the big brutish brother in the lineup. It’s still, of course, incredibly lightweight, but compared to the other options this is an altogether stiffer and more powerful model, aimed towards stronger, aggressive riders in demanding terrain.
There’s a solid piece of CNC Aluminium comprising the Surge’s baseplate, making it substantially more rigid than the Arc, although undoubtedly adding a little to its weight. The highback is also stiffer, although it does still feature the walk mode adjustment, where it can fully hinge back to allow for longer strides touring in the backcountry.

Spark’s T1 system is where the Bozeman bunch have made the biggest waves. The stupidly simple Tesla Snap Ramp and Side Lock makes transitioning from walk-to-ride and back effortlessly simple. It really is as simple as ‘slide and click’.
On the way up, the Surge bindings offer the same 12° and 18° climbing wire positions as the rest of the line and are adjustable hands-free, with the Whammy Bars, which now come fitted as standard (and no longer the costly add-on purchase).
On the way back down, the tougher and more responsive straps coupled with the Surge’s bombproof chassis make this a powerhouse binding for charging big, backcountry lines. If your priority is less on shaving every gram and more about straight lining out the mouth of a couloir on the seat of your pants, there are few better options at your disposal than these.
