http://tinyurl.com/29884 I have this one mounted on my top tube. It's really short, like 14"? but my frame is so small that, with the water bottle in place, I couldn't get it on either of the other two tubes. Also small enough to carry in a Camelback. I read a bunch of reviews on road bike review and MTB review before choosing. It has a little thing that flips out for your foot to stand on, and a handle that also flips out. It has a built-in gauge. I am embarrassed to say, though, I haven't used it yet...It has a single connection around the tube that it clicks into.

I bought BF that tiny Crank Brothers pump that is supposed to inflate to high pressure, but we just can't get it to work right. It's been given up on.
