I know this isn't a pump thread, but here's my thoughts on a pump:

I too am not familiar with the Brompton pump. However, I have a Topeak Morph pump and rarely take it with me. I leave it at home in favor of the much smaller, nearly as efficient Park mini pump http://www.amazon.com/dp/B00188NM4Y/...SIN=B00188NM4Y

I use the Park for MTB, utility, road riding, and anywhere I go with my folding bikes. In fact, since getting the Park a couple years ago, I have not even used the Morph.
