Blackburn: If youre a tubeless tire convert, youll 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 seated, flip the switch back to bypass the chamber and you can top it off accurately with the giant gauge. Now everyone can seat tubeless tires without a garage full of compressors and hoses. The two-position switch means youre charging or youre inflating. Charge the chamber, position one. In position two, that air is forced into the tire. You can now use the Chamber like a regular floor pump. No more hot air. Once youve seated your tire, the switch bypasses the auxiliary air chamber and the direct-to-valve technology lets you pump the tire instantly, without going through the chamber all over again. A riser bar with comfortable grips comes stock, but a regular 31.8mm stem clamp allows you to fit your favourite handlebar for welcome familiarity and sneaky training. No one likes being right next to an inflating tubeless tire, do they? Our 4ft hose lets you keep out of the way, while also allowing you to inflate tires whether theyre on a hitch rack or repair stand, or around the corner. Our huge 2.75in top-mounted gauge lets you easily read the pressure without stooping and the button on the pump head lets you micro-adjust pressure. Works on any type of bicycle value with the flick of a lever.
