A relatively new bike accessory company called Lezyne has been in business for just a couple of years now. Their products are well-thought-out and designed to be practical and useful. Probably their biggest hit has been their line of mini-pumps. We've been stocking the Pressure Drive Small model, and it's proven to be a popular item.
What distinguishes their mini-pumps is a detachable air hose that stows inside the pump barrel when not in use. The hose is reversible to work on either Presta or Schrader valves, without the need to disassemble the pump head to switch modes. Having the flexible hose means that there's less of a chance that you'll rip out the valve from your tube as you're pumping up a flat tire on the side of the road.
There is an optional hose available that also has a built-in air gauge. I found out, though, that the gauge hose only fits inside the Medium or larger models of mini-pumps, not the Small models.
The Lezyne mini-pumps have so far only been available in Black. They've also made some available is Silver, only as an included accessory on select bicycle models, such as the '09 Raleigh Clubman. Now, for those of us who like to match our accessories to all of the fancy-colored components on our bikes, you can get the Lezyne pumps in Red, Blue, or Gold. By special-order; please call us to check availability.
