It's a pain to have two different pumps for road and trail. But now you don't have to worry about it. The Crank Brothers Power Pump Alloy bike pump features a compact design that lets you choose between presta or Schrader valves, so you'll only need one pump no matter where you go.
Dual piston single-stroke pump with settings for high volume or high pressure
Schrader and presta valve heads with no complicated hardware to choose between the two
Comments about Crank Bros. Crank Brothers Power Pump Alloy Silver:
I carry one of these strapped to my mountain bike under the seat on the side. Fairly lightweight. has two settings (twist the pump bottom left or right), one for volume, the second for high pressure. I use the volume setting until I cant pump no more, then I switch to high pressure and fill my tire the rest of the way (I run 30lbs). It takes some work to pump up a tire but what would you expect? Also the pressure gauge is fantastic, but fickle, you have to pump to get a reading, and often I find it pointed in a odd direction to actually read it. This pump easily does Presta or Schrader (twist the pump head left or right).
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
