LezyneCNC TLR Valves(Return to Product Page)Add your own review
I have these installed now on both road and mountain bikes and the CNC components are really top-notch. Never a problem with compatibility with a number of frame and floor pumps. I love them but it's like using a Hummer for a grocery-getter. So much superior to the myriad offerings on the e-commerce sites, and that is how I justify them. They are the epitome of gilding the lily. The best tubeless valve stems, ever. Form, fit and function are first class.
I like Lezyne products they are high quality, very well thought out. This one could use a thicker outside round seal. The thinner rubber seal compressed unevenly and did not hold air. After I changed the seal it work break.
Another point. The 80 mm valve stems could be treaded more. Mine the tread along the stem is a bit short, so compressing the outside rubber circular seal did t work on my 45 mm carbon rims.
yo must have a precise rim width to use these great valves, If your rims are smaller than the valves you will not those valves tight.
A great improvement would be if they can run almost full tread on on stems.
for example, my 44 mm wide rims, will not work with the 80mm Lezyne CNC stem as there are not enough threads to tight the stem to the rim, and the 60 mm will be too short.
If the thread gets extended, they will be the best on the market. period.
