ATK SL Lightweight Brake

The ATK SL Lightweight Brake is a minimalist ski binding engineered for fast, technical touring. Weighing only 135 g, it combines alu 7075, POM and titanium to deliver a very light footprint without sacrificing precise feel. Its compact design pairs seamlessly with any tech boot, making step-in straightforward thanks to the Easy Entry System's reworked toe geometry.

Built around ATK’s Rolling In System, the binding protects its titanium U-shaped springs with two hardened steel bushings (0.4 mm wide) to reduce wear and preserve consistent release performance over time. The fixed race walking mode and fixed race release setting provide a stable, predictable platform on the ascent and a secure connection on the descent. The overall construction is intended for ski mountaineering and long tours where low weight and durability are key.

With its robust materials and efficient entry mechanism, the SL Lightweight Brake excels in alpine terrain and mixed mountain conditions. Its precise release characteristics and secure boot retention inspire confidence on technical descents, while the lightweight build reduces fatigue during long climbs.
