I have the valve stems already. love the convenience. switched my pump also. I bought these to air up my airhorn, as I ride thru town quite often. The whole system works so well! Will be switching other bikes in the future
While not an essential upgrade, it's definitely nice to have and I won't be going back to presta.
If you have clik cores on you bike, this will convert schrader over to clik without issues.
The click on makes it very pump up the tires.
Love these valve heads and the adaptor works perfect on my floor pump
