Review on 🚲 EyezOff GP96A Alloy Mini Bike Pump with Pressure Gauge - Compact and Durable Pump with Mounting Bracket by Michael Ringgold

Advantages: cheap, small and light, easy to mount on the frame, has a built in pressure gauge and it will inflate new chambers if you come across one. The pumping motion is ergonomically awkward (because you have to maintain pressure on the end of the valve to avoid tearing off the valve stem). I doubt you can get anything over 85psi with this unless you are the world's toughest competitor and going from Presta to Schrader is a pain. However, the positives are enough that after my first one was stolen I bought it a second time.
