The Mountain 2Stage Digital Shock Pump features the innovative 2Stage Pressure Selector, which allows you to select high pressure for filling suspension forks and shocks or high volume for inflating mountain bike tires. The integrated easy-to-read digital pressure gauge provides accurate pressure readings up to 300psi / 20.7bar. The Pressure-Rite connector allows connection of both petcock and auto valves, while the flexible hose relieves the valve stems of tire inflation stress. The air release button makes it quick and easy to set the correct pressure.
