Masterfully engineered tubeless bicycle tyre valves constructed from lightweight, durable CNC machined aluminum. The grooved valve cap improves grip, and features an integrated valve core tool and a T25 tip that tightens the valve to a tubeless rim. The valves are equipped with an o-ring and grooved aluminum locknut for a leak-free seal. They are tubeless sealant friendly, provide maximum airflow and offer compatibility with all Presta style floor pumps and hand pumps.
