You could buy a new Schwalbe tube with the Clic valve or if you have a Presta tube with a removable valve core, it can be remove to replace it with a Clic core. It looks like a neat system. There have been a bunch of online reviews and most have been favorable. So, much so that it had been hard to buy Clic products. That has gotten better lately. I will be happy to replace my Presta valves and give this a try. Presta aren't terrible but they are not terrific either.
