I have not liked minipumps, in fact, I still carry a fullsize frame pump on one of my bikes. But with two bottles, the frame pump needs to be under the top tube, where it gets easily knocked off. But the Crank Bros Klic actually works, and it works very conveniently. You thread the hose onto the Presta valve, then you attach the hose to the pump via a magnetic coupling, which is strong enough to not lose air. There is a pressure gauge on the side of the pump, and about 300 strokes will get the tire up over 70 psi, good enough for a 28mm tire. Or, you can unthread the cap and use it (with your own threaded CO2 cartridge) as a CO2 inflator. Just be sure to really tighten that cap back on, as I had a cap unthread on a previous Klic pump (this was a previous version where the cap was not a CO2 inflator). The pump comes with a holder that attaches under a bottle cage, out of the way of the cranks.
