I like Lezyne's mini pump with pressure gauge. I prefer it to gas because I find gas fiddly sometimes and harder to judge pressure.
It seems pretty straightforward to get over 110 psi.
It's 30 cm long, weighs 194 g and has a frame pump mount.That looks good, and I recall it getting a good write up recently.
It's hard to tell how big it is from the picture. Presumably it has a bracket for mounting to the bike, but could it slip into a pocket?
