Details The industry-leading Spark R&D Arc ST Splitboard Bindings are the most popular in the world for good reason- they excel in the trees and powder, but are tough enough to handle more complex all-mountain conditions. Cutout baseplate design, medium flex Asym Rip 'N' Flip Highbacks, and a smaller ankle strap with a flex window combine to save valuable grams and deliver a surfy ride down. This binder is incredibly light weight, simple and easy to use, and super dependable, with a medium flex suited to most riders and great mobility. All Arc ST Bindings incorporate Spark's unbeatable Tesla T1 technology, and new Smooth Touring (ST) Tech is featured on ST Brackets and ST Whammy Bars. These components utilize a proprietary thermoplastic blend that is molded over the metal part reducing friction, increasing durability, and improving touring efficiency. New Pillow Line Straps are made using a one piece construction, are extremely durable, comfortable and waterproof. The highback quickly moves from ride mode to tour mode and the new whammy bars allow you to quickly adjust your climbing wires for the angle of ascent. New this year, almost the entire binding is made in house at Spark R&D in Bozeman Montana. Flex Rating (1 = soft, 10 = responsive) 5-6 Highback Asym Rip 'N' Flip Highbacks New Arc ST Asym Rip 'N' Flip Highbacks have a moderate amount of glass fiber fill for medium flex and a surfy feel. The Asym Highbacks have been redesigned in 22/23 and now feature individual left and right highbacks for improved ergonomics. The upper section of the highback is flatter allowing for increased lateral mobility. All Rip 'N' Flip Highbacks incorporate a tool free forward lean adjuster (FLAD) that easily toggles between tour and ride mode. Heelcup N/A Straps Pillow Line Straps Pillow Line Straps are lightweight, durable, comfortable, waterproof, one-piece molded construction, and made 100% in-house. Arc ST Ankle Straps are smaller around the boot than the Surge ST and feature a flex window for max agility while maintaining support. Toe straps are designed to be used as a toe cap, but also fit nicely as a traditional strap across the top of the boot. Buckles and Plastics Ladders and adjusters are produced in-house with unique thermoplastics that maintain flex over a wide temperature range, performing well on spring tours as well as sub-zero suffer fests. All straps incorporate Burton's time-tested bomber buckles.

Spark overmolds a custom plastic blend over and through the holes in the aluminum base, forming bushings that last four times longer than their previous brass version. ST Whammy Bars The ST Whammy Bar climbing wire is built right into the baseplate. Overmolded plastic where the bar contacts the baseplate allows for super-smooth climbing wire position changes in the steeps. You can switch easily from stowed, to low (12°), to high (18°), and back again while touring. Tesla Snap Ramp T1 System bindings slide sideways into the offset touring bracket and are locked into place with Tesla Snap Ramp. No pins, no cables, no fiddle factor. Integrated Ibex crampon mounting claws on touring brackets make for quick and easy installation and removal. T1 Heel Rest The T1 Heel Rest catches the climbing wire in the 12° and 18° positions and is specifically designed to hold the T1 Step Locker in place.
