Short, fat and good looking. The Sport Drive has plenty of volume to inflate knobbly tyres. Fast. The flexible connector hose lets you choose presta or schrader valves without having to unscrew, modify and reassemble the pump.
A well thought out product minimizing size and weight but maintaining volume. About the size of two Snicker bars. At first sight it looks too small but the overlapping handle hides almost a third of the pump volume. The oversized plunger rod/guide ensures it feels robust and smooth when pumping. The flexible hose means that you are not rigidly stuck on your wheel. Simple serviceable design.
Great pump. Relatively light weight, high volume pump for its nice. Clips on nicely beside th e water bottle holder. Flexible hose prevents snapping valve stems from over vigorous inflation. Looks great too.
Had a small slender compact pump for when I get caught with a puncture & need to inflate the spare. I thought it was good until I pulled the valve stem out of the tube whilst inflating. 90 min wait until wife picked me up. Discarded it and purchased the Lezyne flex hose model from Ground Effect. Longer stroke and wider barrel so you get the job done quicker and to a higher pressure without pulling the valve. No need to limp home on an unsafe 30psi any more.
Very compact and effective pump fits neatly into you jersey pocket or backpack and pump well.Good value unit
This is a compact pump with a flexy house attachment that works well for both valve types. My only reason for dropping a star is because it's hard work to get that last 20 psi into my fixed gear tyres. It's only single action so you have to push hard to inflate your tyres hard. But that's ok, gives you a work out. All in all a really good pump!
