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.
