ZONE3 - Aeroforce-X II Calf Sleeves - Unisex - Black/Red

The Aeroforce-X II Aero Calf Sleeves are engineered to deliver meaningful aerodynamic efficiency gains on the bike, targeting the lower leg, a known source of aerodynamic drag.

Manufactured by NOPINZ, specialists in aerodynamic performance apparel, they are designed for race-day use where marginal gains matter most.

Developed in collaboration with NOPINZ, leaders in aerodynamic garment engineering, the Aeroforce-X II Aero Calf Sleeves are designed to optimise airflow around the calf during high-speed riding.

The lower leg contributes significantly to aerodynamic drag, and refining airflow in this area can improve overall riding efficiency over race distance.

The sleeves use a lightweight, quick-drying technical fabric engineered to support controlled airflow while remaining breathable at race intensity.

Integrated mesh zones promote ventilation and temperature regulation without compromising the aerodynamic profile.

A close, contoured fit creates a smooth interface with the leg, helping reduce turbulence without restricting movement.

A silicone gripper at the upper cuff ensures the sleeves remain securely in place throughout the bike leg, maintaining consistent positioning from transition to dismount.

Designed exclusively for competition, the Aeroforce-X II Aero Calf Sleeves reflect NOPINZ’s race-proven approach to aerodynamic performance.
