The Blackburn Chamber Tubeless Floor Pump seats tubeless tires without needing a compressor. You charge the internal chamber by pumping in the charge position, then flip the switch to dump all that stored air into the tire at once. The blast of air forces the bead against the rim and seats the tire. Once the tire is seated, flip the switch back to bypass the chamber and use it like a standard floor pump to dial in your final pressure. The 2.75-inch gauge mounts on top of the pump where you can read it without bending down.

The pump reaches 160 PSI maximum pressure and works with Presta, Schrader, and Dunlop valves. The 47-inch hose gives you enough length to reach bikes on a repair stand or hitch rack without moving the pump. An air bleed button on the pump head lets you fine-tune pressure once the tire is inflated. The handle uses a riser bar setup with comfortable grips, but the 31.8mm stem clamp means you can swap in your own handlebar if you want something different. The oversized pump shaft moves more air per stroke than a standard floor pump, which helps when you're charging the chamber.

The two-position switch controls whether you're charging the chamber or inflating the tire. In position one, each pump stroke builds pressure inside the chamber. In position two, that stored air releases into the tire through the hose. After the tire seats, you switch back to position one and the pump operates as a regular floor pump for topping off pressure. The pump head has an alloy cap and lever that hold up to regular use. Blackburn backs the Chamber pump with a lifetime warranty and includes the pump body, hose, gauge, and pump head.
