The Mountain 2Stage Digital Shock Pump features an innovative 2-stage pressure selector that allows you to choose between high pressure for filling suspension forks and shocks, and high volume for inflating mountain bike tires. The integrated, easy-to-read digital gauge provides accurate pressure readings up to 20.7 bar / 300 psi. A Pressure-Rite connection enables compatibility with both Presta and Schrader valves, while the flexible hose relieves stress on the valve stems when inflating tires. The air release button allows for quick and easy adjustment to the desired pressure.
