Have this pump in medium.

The bracket mounts underneath a water bottle cage with the pump off to one side. There is no gauge, I keep pumping until the tire feels firm. Unfortunately, had a flat yesterday, so had another opportunity in using the pump. Once home, found I inflated to just 60 psi, so a gauge would be helpful.
