The Topeak Presta Valve Extender is designed for cyclists using deep-section rims, which often require longer valve access for inflation. This extender is precision-machined from aircraft-grade aluminum, ensuring both strength and lightweight performance. Measuring 60mm, it easily screws onto the original valve, providing the necessary length to reach your pump's chuck. A unique rod inside the extender engages the valve's lock nut, allowing you to close the valve and prevent air leakage without needing to remove the valve core. This extender is compatible with rims up to 90mm deep, making it an essential accessory for any serious cyclist.
