Details from Spark R&D:
The Ibex ST Splitboard Crampon maintains the same great shape and functionality as previous models but has been upgraded with ST Tech! We’ve replaced the brass axle with our overmolded thermoplastic allowing for effortless installation and super-smooth rotation. Crampon teeth are fully engaged when used with or without the Whammy Bar for maximum security on dicey terrain. Our dual-width design features one crampon that is slightly wider than the other, allowing the crampons to nest together for easy handling and reduced packing space.
Weight: 5.50 oz/ea (156g) – 11.0 oz/pr (312g) - Regular
Climbing crampons for Arc & Surge (including ST and PRO versions), Magneto, AfterBurner, Burton Hitchhiker, and Nitro Vertical bindings.
Also compatible with Heel Lockers and Riser Kits.
