ENVE partnered with the renowned inflation artisans at Silca to create the dependable Silca Valve Extender. While a valve extender isn't the most glamorous accessory you'll buy for your bike, your ENVE rims will take much less time to inflate without you having to search for a lost valve rattling around. The extenders are compatible with any tubular or non-tubeless clincher rim from ENVE and tubes or tires with removable valve cores. And let's face it — if anyone can design a tiny part that functions the way you need it to, it's Silca.
