The Lezyne CNC TLR Valve PRO is designed for road, gravel, and mountain bike riders seeking a high-performance tubeless setup that handles high sealant volume and tyre inserts with ease. Engineered from lightweight, durable CNC-machined aluminium, these valves feature a smart, high-flow architecture that prioritizes reliable inflation and maintenance. While these valves offer superior airflow, riders should note they are specifically designed for Presta-style pump heads and require careful installation to ensure the rubber O-ring creates a perfect, leak-free seal against the rim.

No, the valve cap includes a built-in T25 tip for tightening, and the locknut can be tightened by hand.
Yes, the valves are fully compatible with Presta-compatible CO2 inflators.
It is recommended to clean the core every few months or whenever you add fresh sealant to prevent buildup.
Yes, they are available in various colors including Black, Gold, Blue, and Red.
No, tubeless tape is required to seal the spoke holes of the rim for a proper tubeless setup.
Check that the O-ring is correctly seated against the rim and tighten the aluminium locknut by hand.
Ensure the valve core is fully tightened and not obstructed by dried sealant; clean the core using the integrated tool if necessary.
Ensure the valve base is flush with the rim and verify the O-ring is not compressed unevenly.
To install, insert the valve through the rim hole and secure it using the grooved aluminium locknut. Ensure the O-ring is positioned against the inner rim surface before tightening to create an airtight seal. Avoid over-tightening with metal tools, as hand-tightening is typically sufficient. For care, occasionally remove the valve core using the integrated tool in the cap to clear any dried sealant buildup. Always ensure your pump head is set to Presta mode before attaching it to the valve to prevent damage to the valve stem threads.
