The Blackburn Chamber Tubeless Floor Pump is specifically designed for tubeless tire set ups. After pumping the side chamber up to the air pressure of choice, you can release it into your tubeless tire, giving it no option but to seal and air up. Once the tire is seated, you can then flip the switch again to revert it back to a normal pump to allow you to pump your tire to the appropriate psi.
