Since the Italian era, this Presta Chuck 17-4 Stainless Steel has updated the Presta Head, which is also a symbol of SILCA.
The efficient push-on construction ensures that the valve is secured without the need for lever or button operation. Due to the unique internal structure of the gasket, the more air pressure is increased by pumping, the more the part that fixes the valve is compressed, and the more pumped, the more reliably the valve is held, so even when pumping to high pressure can be done without stress.
