Lezyne CNC Pro Tubeless Valve

The CNC TLR VALVE PRO are precision-engineered tubeless valve stems for road bike, gravel bike and mountain bike setups, constructed from lightweight, durable CNC-machined aluminum. Their clean, stylish design complements the look of modern bicycles. Featuring a four-slot, high-flow system, these tubeless valve stems allow seamless air and sealant flow-even when used with tire inserts. The innovative, slender base geometry ensures compatibility with narrow inner rim widths.

The valve cap features an integrated valve core tool and a T25 tip for tightening the valve to the rim. Additionally, machined grooves in the cap improve grip during use.

The valves are equipped with an O-ring and grooved aluminium locknut for a leak-free seal. They're tubeless sealant-friendly, designed for maximum airflow, and offer compatibility with all Presta-style floor and hand pumps.
