The Presta Pro Head is a premium, fully CNC-machined pump head designed to pair perfectly with Lezyne HP (high-pressure) and HV (high-volume) pumps. An easy-to-use, slip-on pump head designed for Presta-only applications - the ergonomic, slim, aluminium lever is actuated to securely lock the Presta Pro Head onto the valve for reliable high-airflow inflation. The innovative Valve Bleed System (VBS) engages the valve pin allowing for fine-tuning tyre pressure- Simply push the VBS button to release air from the tyre to achieve the desired pressure. Engineered using corrosion-resistant brass internals and a robust aluminium body with a gloss silver anodised finish.
