> 3 dayThey installation was simple. The rubber ring was a nice addition to keep the seal air tight. Good to know you can get good quality tubeless components without spending a small fortune.

> 3 dayIve gone through a lot of valve stems in my time using tubeless tires. These are by far the best-built Ive seen - a bit more substantial than other brands Ive used. They also have removable cores, which is huge for those of us adding sealant without wanting to pop the tire bead off. Im going to see if they have a 60mm length version for use with more aero-style rims.

> 3 dayFor the money, these are hard to beat. I liked the first pair so much that I purchased another 3 for the other wheel sets I was setting up tubeless. Work as well, if not better, than the bigger brand name valves.
