Easy conversion: The valve nut solves problems caused by valves without spacer rings, which can make inflation difficult. The conversion nut lets you convert the valve for smooth inflation, suitable for any biking adventure. Improved performance: Addresses excessive clearance when mounting the inner tube directly. Its tight internal thread replaces the original steel nut of the French inner tube, providing secure fit and improved performance. The O ring protects against scratches and seals the connection. Convenient installation: The rim valve conversion nut comes with an installation wrench, making setup hassle . It is designed to be waterproof and mud proof, ensuring durability on long rides. Secure installation reduces vibration and loosening. Versatile compatibility: The installation wrench also installs and removes the detachable French standard valve core and extension rod. This allows quick switching between valve types to suit your riding needs. Use scenarios: Road or gravel bikes with French/Presta valves lacking spacer rings, for easier inflation. Bikes with worn inner tube nuts that cause looseness, especially in wet or muddy conditions. Touring or MTB setups that use detachable valve cores and extension rods for flexible inflation options.
