LezyneCNC TLR Valves(Return to Product Page)

Overall, these work as they should for my tubeless setup. Was able to remove the valve core easily with the cap (nice feature, btw), add sealant, and it holds air. The thick collars are easy to tighten and look nice, but ended up being too thick for me to fit a pump head onto the valve. I have 50mm wheels, a fairly common depth, and figured the 60mm valves should work. They do, but I had to use a standard collar from a spare inner tube. If the valves were around 65mm they'd probably work without issue, and would be 5 stars.

The threads don't go all the way down the valve stem, which means if your rim isn't deep enough the threads stop and you can't tighten it in place. Now I have to order a different set because I ordered 80mm instead of 60mm. Even if I had bought the ones that would work on my gravel bike, the shorter rim depths on my other bikes means they won't work with those wheels.

I really like the fit, finish and function so far of these tubeless valves. So far I haven't had any issues with clogging, but time will tell.

I Just installed these when I changed tires on my gravel bike. I appreciate the multi-function valve cap which can be used both to remove a valve core as well as a means to tighten the seal on the inner rim. They appear to have sealed perfectly. I will order another set so I will have them on hand next time I need to replace valves.

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.

After many trials and errors with other valves in the market, I found Lyzene valves. A problem free valve. The cap is used to to remove valve stem and refill sealant. Great valve,

These valves are outstanding. The cap serves as tool for valve core removal as well as tightening the valve down into the hole securely. I'll definitely go with these again with another tubeless setup.

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.
