CLIK valve system - 

Clik valves are a modern upgrade to traditional Presta valves, designed to make inflating tyres faster and more convenient. Instead of the fiddly screw top on a Presta, a Clik valve uses a spring-loaded push mechanism that automatically seals when the pump head is removed. This means there’s no need to unscrew or re-tighten the valve core each time you add air, reducing the risk of air loss and making the whole process much quicker. The main benefit over Presta valves is ease of use—especially in cold or muddy conditions where handling the tiny threaded tip can be awkward. Clik valves also tend to form a more secure and reliable connection with modern pump heads, improving inflation efficiency and reducing wear on both the valve and the pump.
