Review on Efficient Schwinn Bike Pumps: Foot and 🚲 Hand Operated, with Presta and Schrader Valve Options by Jim Booth

The Presta valve has been around since the 1890's. Exactly how Schwinn managed to screw up *F* a technology that's been around for over a century, for which pump designs have been around for just as long, I suppose, is beyond me. They didn't have to invent anything, just produce. And they failed. This pump has a stranglehold on the Presta valves, making it impossible to remove the pump head from the impeller without great effort after inflating the tire. I've broken valve stems on every bike I've pumped with this thing. Thankfully, continental valve stems are interchangeable, since tubular tires are $100 each. Terrible product
