CHALLENGE Presta Valve Extenders
Challenge Presta Valve Extenders thread into your existing valve stems to reach through deep profile rims for easy inflation. They are compatible with tubes and tubular tires that feature removable presta valve cores – simply remove the presta core, install the extender and re-install the presta core in the extender. The two anodized aluminum extenders use rubber gaskets to achieve an air-tight fit and the kit includes a simple plastic installation tool.
Please note Challenge Presta Valve Extenders are compatible with our Challenge Latex Inner Tubes and all Challenge Tubular Tires and may be required for use with deep section rims.
