OFA Tubeless is designed to satisfy the new trend of tubeless tire, which requires large & instant amount of air to seat the beaded wall of tubeless tire. The traditional, intermittent & small air volume pump cannot serve the purpose. Beto OFA Tubeless takes only 8 strokes to pressurize the burst tank inside the barrel that can seat the tubeless tire up at roughly 10- 15psi. A patented air channel system allows user to keep pumping more air directly into the tire and monitoring the pressure in the burst tank and tire via an oversized 4 ” gauge. It revolutionizes the century-old bike pumps.
