Transform your existing wheels with this Schwalbe CLIK Valve Conversion Kit. Perfect for cyclists who already own a Schwalbe CLIK Valve pump head or adapter, this two-piece set lets you retrofit your wheels without replacing them entirely. Each SV (Presta) based valve threads directly into your valve body, replacing the traditional presta valve core. Compatible with standard Presta pump heads that use rubber gasket compression fit—just note that threaded pump heads aren't supported. Upgrade your inflation experience with the convenience and reliability of Schwalbe's innovative valve system.
