Tubeless valve set - part of Schwalbe's innovative Clik system.

With the SCHWALBE CLIK VALVE, pumping up the bike valve is very easy - with just one click. The SCHWALBE CLIK VALVE can be operated with one hand and is child's play to use. What do you need? The valve and the corresponding pump head or pump head adapter. The Clik valve can be clicked onto the bike valve with minimal force and removed very easily after successful pumping. The Clik Valve tubeless valve even has an additional advantage: a 50% higher airflow than conventional tubeless valves. It thus combines several advantages.

• The valve insert and the pump head or the corresponding adapter together make inflation child's play.
• It can be operated with just two fingers and is extremely simple for everyone.
• There is no longer any risk of air loss and there are no signs of wear on the pump head.
• The air flow in conjunction with tubeless is 50% higher than with conventional SV valves.
• Conversion kits for all common bicycle valves & adapters for car valves are available

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.

Note: Click Valves can be inflated with normal SV (Presta) pumps, but a Clik Valve pump head is required for full performance benefits.
