The Crankbrothers Alloy Power Pump is one worth considering if you want a single pump to take out on all your bikes. While it lacks the outright pushing power of some mini pumps the switchable stroke volume, useful pressure gauge and easy-to use twin head make it a good choice if your stable spans road and dirt.
At the best part of a foot long this isn't a lose-it-in-your-jersey mini pump by any means, but a deep pocket will swallow it, or you attach it to your frame: the mount doubles as a protective cover for the head, which is a good idea if a little fiddly. The presta and Schraeder heads are opposite one another, and to use either you simply twist the head in the chosen direction and start pumping.
The Power Pump has a switchable stroke and you twist the base to select either high volume or high pressure. High volume is good to about 40psi and is great for MTB tyres; high pressure is for skinny rubber and tops out at 130psi in magic fantasy land (the packaging) and about 100psi in the real world. You can of course combine the two, starting off on high volume to get the tyre up quickly, then switching to high pressure to get things nice and firm. That'll save a bit of time on the roadside.
Because the pump attaches directly to the valve you need to be a bit careful when you're going after it so as not to damage the tube, but the wide head is fairly easy to support with your spare hand. The gauge is accurate enough to be useful and big enough to be easily legible, and the build quality is generally good although there's a fair bit of wobble in the shaft when it's fully extended. So to speak.
Pumping up a 24mm tyre from scratch took 30 strokes on volume followed by 120 on pressure; that gave us a usable 85psi and the pump's good for a bit more if you've got the time or inclination. A big MTB tyre takes a fair while to go up but the Power Pump never struggles, and it's good for hybrid tyres and pretty much anything else. It's not the most ergonomic pump ever and it's hard work getting road tyres really hard, but since it can turn its hand to all your steeds it's certainly one to consider.
Good all-purpose pump for trips on all your bikes, struggles over 90psi
