300% INCREASED AIRFLOW: Revolutionize your tubeless setup with an internal design that delivers up to 3x more air volume than standard valves. This massive airflow allows you to "seat" tubeless tires effortlessly with a standard floor pump, saving you the need for a compressor CLOG-FREE PERFORMANCE: Say goodbye to sealant-related headaches. The oversized opening and robust design prevent tubeless sealant from gunking up your valves, ensuring a smooth air path and consistent pressure readings every time you ride UNIVERSAL PUMP COMPATIBILITY: Total freedom at the pump. The CoreCap converts your Presta valve to work instantly with Schrader (car-style) pump heads without needing extra adapters, while remaining fully compatible with your existing Presta floor pumps BEND-PROOF DURABILITY: Eliminate the frustration of snapped or bent valve pins. By replacing the fragile traditional core with a solid, high-grade anodized aluminum structure, the CoreCap provides a rugged system that withstands heavy-duty use ALWAYS READY TO INFLATE: Skip the hassle of unscrewing tiny nuts. This innovative system is always open for airflow but sealed against the elements, making mid-ride adjustments faster and more convenient than ever before
