Lezyne CNC TLR Valve Pro

Yes. The four-slot, high-flow design is specifically engineered to ensure air and sealant can move freely even when you are running tire inserts, which can sometimes block airflow in standard valves.

You should choose a stem length that extends at least 15-20mm above your rim profile to ensure your pump head can securely attach. If you have deep-section aero rims, you will likely need the 60mm or 80mm options, while standard rims usually work fine with the 44mm version.

No, you don't. The valve cap is cleverly designed with an integrated valve core tool and a T25 tip, so you always have the necessary tools for installation or roadside adjustments right on the valve itself.

The valves feature a grooved locknut paired with an O-ring, which creates a secure, airtight seal against the rim bed. This setup is designed to prevent the common issue of sealant weeping or air loss at the base of the valve.

They feature a slender base geometry designed to fit a wide variety of rim shapes and widths. However, if you have a rim with an unusually deep or oddly shaped valve hole, it is always worth double-checking your rim manufacturer's specifications.
