Reviews
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.
