I am relatively new to tubeless. Stans seemed to me to be the standard. However, when I tried to use my KOM Cycling injector system to check and inject sealant into my tires I discovered a real problem with these valve stems. They narrow near the bottom, so the injector tube could not extend into the tire. Attempting to inject sealant simply didn't work. Lezyne Tubeless valve stems, on the other hand, do allow the injector tube to fully extend into the tire. This KOM system allows you to remove, test, and reinject sealant into the tire without having to break the tire bead seal. I had to remove the Stans and replace them with the Lezyne.
Updating really old tubeless tires and valves (and setting some up tubeless). These were great, were delivered quickly and at a very good price.
Great light weight choice for tubeless set ups. No issues with leaks, easy to remove/replace cores. Choice of colors is added bonus.
I have used stan's product since they came out. I have used other brands but always come beck to stan's because you can be sure of what you get.
Looks good. Works.
