And you thought you'd never get big air... If you're a tubeless tire convert, you'll wonder how you lived without this pump. Just pressurize the chamber and with a simple flip of the burly switch, all that air floods the tire, giving it no option but to seal and air up. Once the tire's in place, flip the switch back to bypass the chamber and you can top it up accurately with the giant gauge. - Oversized pump shaft for extra durability. - Pump head features rugged alloy cap and lever. - Super long 47" hose to reach valves in stands or car racks. - PSI and Bar increments on gauge, with vibrant color matched background. - 160 PSI, 11.3 Bar maximum - 3150 grams / 6.9lbs.
