I bought into Clik when I first saw them advertised. These came as a bonus when I bought a digital pressure gauge and were added to my collection of extra Clik cores. I recommend them and tell my friends about them frequently.
Threads seem to have been cut in a hurry and they dont really thread on easily. Almost feel cross threaded. They do match my bike and car color however.
Just received this upgrade last week. The install on my old pump was extremely easy as was the replacement of the tube valve core. I love the simplicity of filling up the tires with my floor pump. I do have some concern about using my frame pump to fill up the tubes since my frame pump does not have the new pump head. It works, but it seems to be much harder to get air into the tube. Could be my imagination but that was my first impression. I am glad that a presta head still works with the new valve cores. I can at least get enough air in to get home (I think).
Easy and fast to check your pressure and inflate your tire. Your old caps work too!
