Asym Rip 'N' Flip Highbacks
Our NEW Arc ST Pro Asym Rip ‘N’ Flip Highback is made from carbon-reinforced nylon in a ratio designed for medium flex and a surfy feel. This material blend is more responsive, lighter, and stiffer than our standard glass-reinforced highbacks. The Asym Highbacks have been redesigned in 22/23 for improved ergonomics, mobility, and durability. All Rip ‘N’ Flip Highbacks incorporate a tool-free forward lean adjuster (FLAD) that easily toggles between tour and ride mode.
ST Touring Brackets
ST Touring Brackets incorporate the best features of aluminum and thermoplastics. We overmold our 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.
Pillow Line Straps
Arc ST Pro Pillow Line Straps are made with premium Pebax® plastics. They 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 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.
