And you thought you'd never get big air! It works on any type of bicycle valve with the flick of a lever. No leaking, no fuss. Clean and simple.

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.

Features:

• Tubeless seating - Quick, reliable, tubeless inflation. Now everyone can seat tubeless tires without needing a garage full of compressors and hoses
• Air bleed button - Button on the pump head micro-adjusts pressure
• Charge switch - You're charging or you're inflating. The two-position switch allows you to charge the chamber in position one. In position two, that air is forced into the tire. You can now use the chamber like a regular floor pump
• Hold tight - A riser bar with comfortable grips comes stock, but a regular 31.8 mm stem clamp allows you to fit your favorite handlebar for welcome familiarity and sneaky training
• Aviation gauge - Blackburn's huge 2.75-inch top-mounted gauge lets you easily read off the pressure without stooping
