A little off topic, but I with a recent flat on my neighborhood commuter bike (first one since I’ve owned it), I discovered a nice feature with the pump I’d purchased to mount on the bike but hadn’t ever used. It’s just a department store pump. But when I had to use it, I discovered that it’s adjustable in that one setting is for high volume, low pressure…i.e. the beginning of pumping up. Once it’s mostly full with bit of pressure, you switch it over to low volume, high pressure setting to complete the inflation of the desired higher pressure.
