I have the
Crank Brothers Power Pump and man do I regret buying this one. I bought it for road use and it just can't get the job done at road pressures. Too much pumping involved. Maybe it will be better for the MTB I am about to build. Basically it works but to get any volume of air you have to pump and pump and pump. Luckily I use CO2 primarily so I use this pump to start tubes for installation and would use it if I ran out of CO2 to get me home (probably at a lower pressure).
