HIRAME This is a pure Japanese pump head that has been loved by many professional mechanics and cyclists for over 30 years. The valve can be easily attached and detached by opening and closing the cam lever, and it has a built-in air backflow prevention valve that allows smooth air filling even at high pressures. The horizontal cam can be operated comfortably even when the space above the valve is limited, such as with disc wheels or small diameter wheels. By replacing the valve adapter (sold separately), it is also compatible with American, British, and bicycle racing valves. For secure attachment to the hose band, we recommend the British-made Jubilee hose band (sold separately). *A Buddhist valve adapter is included as standard. *Depending on the lot, the hose tube may be plated, but there is no difference in functionality or materials from conventional products. Recommended hose inner diameter: 6mm to 8mm
