The Birzman Valve Extender II 80mm With Tool (2 Pcs) is a specialised bicycle wheel accessory designed to extend the reach of Presta valves on deep-section and high-profile bicycle rims. When a standard valve stem is too short to provide convenient access for tyre inflation, this valve extension helps bring the valve opening within easier reach, making it more convenient to connect a compatible bicycle pump.
Advanced Features and Benefits
1. Extended 80 mm Valve Reach
The 80 mm extension helps increase the effective reach of a compatible Presta valve. This is particularly useful when deep-section rims make it difficult to access the original valve stem with a pump.
2. Designed for Removable Presta Valve Cores
The Birzman Valve Extender II is intended for Presta valves with removable valve cores. The valve core must be removed during installation and reinstalled according to the manufacturer's instructions. Confirm your valve type before purchasing to ensure compatibility.
3. CNC-Machined Aluminium Construction
Made from CNC-machined aluminium, the extender offers a lightweight metal construction designed for bicycle wheel applications. This makes it a practical option for cyclists looking to extend valve reach without adding unnecessary bulk.
4. Valve Core Tool Included
The set includes a tool for removing and reinstalling compatible valve cores. This accessory supports the installation process and helps keep the required tool available when fitting the extensions.
5. Improved Access for Tyre Inflation
By extending valve reach beyond the rim profile, the extender helps make it easier to connect a compatible pump head. This can be especially helpful when maintaining deep-section road wheels and other compatible high-profile rims.
6. Convenient Two-Piece Set
The two-piece configuration provides a convenient option for cyclists maintaining compatible wheel setups that require extended valve reach. Check the supplied product configuration before installation.
