I know this has been written before, but I just wanted to sing the praises of the Topeak Road Morph w/guage frame pump.
I have recommended this pump to many people, but had never used one myself. I finally got one, put it on my bike Friday and had two flats today. The pump got my tires up to 120 psi with ease. It's easy to use, too.
If I have a complaint, it's the hanger system. Speedlever has mentioned this in Bengeboy's thread on Mt. St. Helens. You are somewhat limited to placement, unless you want to give up a water bottle. They recommend running it under the top tube, but if you have a swoopy-framed bike like my Giant, that won't work. I used their twist ties and have it roughly where my old pump was (the old pump would work with the bottle cage). Speedlever says there is a new hanger coming out. I will look for it.
But, the pump is great.
