However, it was not enough to just shrink the Impero; the Pocket Impero adds some impressive technology of its own. The unique Slide-Lock Silicone Insulating sleeve both improves grip while protecting hands from the heat of pumping to high pressures (another issue for 'mini' pumps) and when finished, slides back into place to double as a handle lock when in your pocket. Mirror honed internals allow for the highest pumping efficiency and lowest stroke count of any pocket (mini) pump. The result: We have you back up and running in fewer strokes, with less headache than any other...Just be sure that once you amaze your riding partners by fixing that 5th flat of the day in record time to remind them that it's NOT a 'Mini-pump'. Notes: Pocket Impero is between a high pressure and high volume pump. Mostly, it is an efficient pump which does not suffer from efficiency loss when hot, which is why most of them don't work so well. At 200 strokes the Pocket Impero reaches higher pressures than any other pocketable pump ever tested in the BikeRadar test protocol, meaning that it is pushing more air with fewer losses than pumps of either high pressure, or high volume designs.
