Zone3 Aeroforce-X II Calf Sleeves

Zone 3 Aeroforce-X II Calf Sleeves Created by Zone3 in collaboration with NOPINZ, specialists in aerodynamic performance apparel, the Aeroforce-X II Calf Sleeves are engineered specifically for race-day use. By optimising airflow around the calf at high speeds, they help reduce turbulence and improve overall riding efficiency over the full race distance, an advantage that adds up during long or fast bike legs. The lightweight, quick-drying technical fabric supports controlled airflow while remaining breathable under race intensity. Integrated mesh zones enhance ventilation and temperature regulation without compromising the aerodynamic profile, while the close, contoured fit creates a smooth interface with the leg for consistent performance. A secure silicone gripper at the upper cuff keeps the sleeves firmly in place from transition to dismount, ensuring reliable positioning throughout the bike leg.
