Pair of 40mm Threaded Valve Extenders

Pair of 40mm Threaded Valve Extenders is a practical cycling accessory designed to extend Presta valve length for deep-section bicycle rims. Ideal for road bikes, triathlon bikes, gravel bikes, and aerodynamic wheelsets, these valve extenders make tire inflation easier when using deep-profile carbon rims and performance wheels.

Built with lightweight and durable alloy construction, these threaded valve extenders provide secure attachment and reliable airflow without compromising tire pressure performance. The 40mm extension length is suitable for riders using medium to deep-section rims that require additional valve reach for pumps and inflators.

Designed for simple installation and dependable performance, these valve extenders are ideal for cyclists upgrading wheelsets, replacing existing extenders, or improving tubed and tubular tire accessibility on aerodynamic rims.
