Muc-Off has renewed its tubeless valves! The new Big Bore valves are designed for maximum airflow, as the valves have no core and are therefore fully open. 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 30mm, total length 60mm, recommended rim depth <20mm. Hybrid is for Schrader pumps.
