Silca EOLO IV CO2 Regulator

The Silca EOLO IV CO2 Regulator is the latest iteration of Silca’s famous EOLO: the first ever CO2 regulator head, developed in 1982. A new, easy-to-grip turn dial allows for full control over the flow of CO2, meaning you can keep it closed until the head is firmly threaded onto the valve. Once ready, open it gradually, with the option to stem the flow once the inner tube is back up to your desired pressure, or the tubeless tyre is seated on the rim.

The neck threads into the CO2 cartridge, eliminating the need for a bulky regulator body to hold it in place – just pop the head into your jersey pocket it case of emergency. It’s also possible to press a Presta valve or thread a Schrader onto the valve port, ensuring this head will work for a wide variety of bikes.

Made from full metal, with no plastic parts to break or erode, this durable head is an efficient, portable solution for smooth roadside inflation in seconds, helping you to get home safely every time.
