I'm after a light pump that can really move air fast - doesn't need to be big, just one you can pump fast without looking like a teen with his internet unlocked for the 1st time. Can be up to 18" long as long as it's light. It needs to be enough to seat UST/TLR that's well fitted, the sort of fit that a track pump seats in a few pumps.
What's good? Been ages since I bought a pump and they vary so much. Had a topeak mini master-blaster that was suprisingly good for a small pump, until it ate my valve core and got jammed up.
