In 1982 SILCA developed the first regulated CO2 inflator. Giving riders control over the flow of gas into the tyre was the key to CO2 becoming the roadside standard, and EOLO IV continues that tradition with a dial design that gives precise control of airflow. Add some air, check the pressure, add more, rather than one all-or-nothing blast that freezes the cartridge and your fingers.
