The ingenious BioLogic Zorin PostPump integrates a powerful floor pump with a seatpost. The pump is always ready to go, hidden from the elements, thieves, and your own forgetfulness. To use the pump all you do is remove the seat post from the frame, attach the valve, flip out the foot peg, and start pumping using the saddle as the handle. Go over 100 psi in less than half the strokes of the best mini pumps.
