The revolutionary 'straight through' coreless design delivers up to 254% more airflow than traditional Schrader valves. Featuring a lever-operated ball valve that revolutionizes airflow control. No blockages, faster tubeless setup, and adjustable tire pressure on the go for any terrain and in all conditions. Stem Length 35mm, total length 65mm, recommended rim depth 20-25mm. Hybrid is for Schrader pumps
