If you're a tubeless tire convert, you'll wonder how you lived without the Blackburn Chamber Tubeless Floor Pump. The pump features two modes (operated by a switch): Charge and Pump/Release. The latter Pump/Release mode enables this pump to operate as a conventional floor pump. But the magic happens with the Charge mode when it comes to overcoming the challenge of seating a tubeless tire on the rim. In Charge mode, you'll pump air into the built-in reservoir and with a simple flip of the burly switch back to Pump/Release mode, all that air floods the tire at once, giving it no option but to seal and air up. The AnyValve pump head is compatible with Presta, Schrader, and Dunlop valves and the 47" long hose makes it easy to inflate in hard to reach places, such as a work stand or car rack. And for those want the option of a truly custom handle, the Chamber Tubeless pump arrives with a 31.8mm mountain bike riser bar, with grips, installed as the pump handle. The handle's clamp mechanism is the same as a stem, so you have the option to swap the existing handlebar out with one of your own liking for a truly personalized approach to tire inflation.
