BioLogic™ Zorin PostPump seatpost
The award-winning BioLogic™ Zorin PostPump is an ingenious combination of a seatpost and powerful floor pump. The pump mechanism is hidden inside the seatpost so the pump is always at hand, hidden from the elements and thieves. The high capacity BioLogic™ pump can inflate a tire in as few as a dozen strokes and can easily reach 110 psi. Ergonomically, the PostPump is just like a floor pump: you stand while you pump and use the saddle as a handle. So say good-bye to crappy mini-pumps, kneeling in the dirt, and arm cramps. Dahon patented technology.
