The A2022 is our top choice for a low-friction, fast-rolling, double sheave pulley. Designed for dinghies, windsurfing, and kitesurfing, it is lightweight yet durable, making it ideal for smaller diameter lines. Our patented bearing system features twin rows of stainless-steel ball bearings on a stainless-steel rail, providing exceptional load-carrying capacity and longevity. The 20, 30, and 40mm Dynamic blocks also utilize our patented Ultra-Strap, strengthened by a unique coining process for increased reliability and rope-friendliness. Additionally, the 20 and 30mm blocks feature a large central rivet for a lighter weight and rope-friendly attachment, perfect for use in cascade systems.
