These caps will generally last longer than the plastic ones. However, their thread is long so it takes a while to unscrew the cap and **** it back on. Also, the wings grabbing the core are thin and extended, suggesting some fragility.
The cores were easy to install. The ease to fill tires is incredible and there’s no loss of air pressure when disengaging the head of the pump from the stem.
Easy and it's solid.
i was waitng for presta replacement or some type of innovation for a long time, this seems to be it. very easy to install and even easier to pump. holds the air well.
In the last few years I’ve gone from Presta to Fillmore back to Presta and am now trying Clik. I particularly like how the Clik valve cores close before the seal is broken so there is no air (or sealant) movement through the core upon removal of the pump head.
