Schwalbe Airmax Pro Digital Pressure Gauge

You probably have a floor pump with a gauge on it, but you may not trust that number. Even if you do, that pump gauge doesn't do you much good on the road. Let's say you fix a flat on a ride with a frame pump. How are you going to know if you're back to road pressure? Or maybe you're running tubeless and you get a puncture. It seals itself, but you don't know if you lost enough pressure to make it worth popping a CO2 canister to ride home on.

Enter the Schwalbe Airmax Pro. This digital pressure gauge is very precise, measuring pressures up to 160 psi (11 bar), and is suitable for both Auto/Schrader and Presta valves. It's got a single button and a single watch battery, so it's foolproof to use and weighs less than two ounces. Keep one in your jersey pocket, your glovebox, or your garage. Can't hurt, right?
