There are pretty much 2 ways to tell if your bicycle tire is inflated: use a gauge or pinch it and guess. One is obviously more accurate, while the other is certainly more portable, since, you know, it’s your fingers. But now let’s add option number 3 to the mix. Tattico Bluetooth is a mini pump that will happily go on any cycling adventure and pairs its internal gauge with your smartphone to give you pressure readings accurate to .5 psi.
After the original Tattico, people wanted a mini pump with a gauge. The problem was getting an accurate readout in a small enough package. So instead of displaying the psi on the pump itself, why not use that screen that everyone is carrying around anyway? It’s a smart piece of innovation from Silca, the same company that first put gauges on bike pumps to begin with. – $120
