After about a decade, my old Joe Blow pump, which I really liked, began leaking somewhere that the standard repair kit did not address. Reluctantly, I decided to spring for the Sport III, and it actually turned out to be a great improvement. It inflates my tires quickly, seemingly with less effort. I find the locking lever on the pump head much easier to use than the old model.
Road tires, beach bike tires, and yes even my car tires! Excellent non-fatiguing resistance and visible pressure indicator. I suggest caution inserting the pump clamp to the valve stem as it is all plastic and one never knows how sturdy it may be. Otherwise looking forward to a long life durable easy to use pump.
Ive owned several versions of the Topeak Joe Blow floor pump and this one is my favorite. Easily identified Presta and Schrager valve connectors. Love the big numbers on the dial. I can easily see the pressure even without my glasses!
