Chamber Tubeless Floor Pump

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. Works on any type of bicycle valve with the flick of a lever. No leaking, no fuss. Clean and simple.

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.
