LEZYNE CNC TLR VALVE PRO:

The LEZYNE CNC TLR Valve Pro is a premium high-flow tubeless-ready Presta valve system engineered for cyclists seeking lightweight durability, precision airflow management, and refined modern styling. CNC-machined from lightweight yet exceptionally durable aluminum, these precision-crafted tubeless valve stems combine sleek aesthetics, rugged reliability, and race-ready performance for road cycling, gravel riding, mountain biking, endurance racing, bikepacking, and aggressive trail use.

Its innovative four-slot high-flow architecture promotes unrestricted airflow and seamless tubeless sealant circulation, even with modern tire insert systems installed. This airflow-optimized design supports efficient inflation, dependable pressure delivery, and consistent sealant flow for high-performance tubeless wheel setups.

The CNC TLR Valve Pro also features an integrated valve cap with a built-in valve core tool for quick maintenance and streamlined trailside adjustments. A built-in T25 tool tip allows direct valve tightening at the rim, while machined grip grooves improve handling during setup and inflation. Designed for dependable leak-free sealing performance, the valves use a cone seal, durable O-ring interface, and grooved aluminum compression locknut to create a secure airtight fit. Compatible with all Presta-style floor and hand pumps, they integrate seamlessly with road, gravel, XC, trail, enduro, and downhill tubeless bike setups.
