Silca's Tubeless Valve Extenders are made from the finest cold drawn aluminum bar instead of the common hollow extruded bar, making them 50 - 200% stronger than normal alloy valve stems. They're 40 mm in length and work with standard or tubeless valve stems with removable valve cores. A pair of high-strength silicone Speed Shields are included with the valve stems, creating less air resistance around the valve while also protecting your carbon or alloy rims from getting marred by the valve nuts.
40 mm length. Compatible with removable-core valve stems only. Valve cores not included.
