The Sphinx Pro is a super-compact, lightweight pulley with fixed side plates. It shares its design with the Sphinx but sets itself apart with sealed ball bearings, delivering greater efficiency. This versatile pulley is designed for high-speed, intensive use, yet remains conveniently small and light enough to be carried on your harness or packed for ski touring and mountaineering. One of its unique features is the ability to accommodate a prusik knot on one side (using aramid cord is recommended), making it an excellent choice for setting up a haul system on a route or handling crevasse rescues, a capability not commonly found in pulleys with fixed side plates.
