zefel hpx is my choice.

I have a Topeak Master Blaster Road. It fits in the frame like a Zephal frame pump but it pumps significantly easier and faster as well.

I've been looking all over to get some more but I can't find them.

I'm a Blackburn fan, myself.

Have any of you tried the Shock pumps? http://www.topeak.com/products/pump_shock_lead.html

The pocket shock (without the gauge) is pretty useless. No gauge so you don't know how much air you are putting in and it's really tiny so you end up pumping for a loooooooong time ;) The other one might be okay.

I got the Blackburn Air Stik and it works pretty well. Dig the handle that flips into a "gun" style.

Topeak Road Morph.

My crank bros mini ruined no less than three tube valves. It has since been relegated to my 3yr old's toy portfolio.

Here's the TRM in action:

The laws of physics can't be violated no matter who makes the pump.

It comes down to pressure and volume.

To put 100psi of pressure in a tire, you need a skinny pump. If your pump has a 1/2 sq.in. section, you have to push the handle with 50 pounds of force to get to 100psi. That's one of the reasons why a Road Morph is so highly recommended. It lets a smaller person push downward on the pump so they don't have to rely on brute muscle power.

A longer stroke will allow you to get more volume with every stroke so a long skinny pump is going to be advised if you want to pump up a road tire quickly and easily.

For pumping up mountain bike tires I like to use a pump that has a fatter section so that I don't have to pump so many times to get the greater volume of air that's required for fatter tires. A pump with a 1" section is fine because you don't pump a mountain bike tire up to 100 psi.

Pumps that don't have a hose pose an additional risk. If you don't stabilize the valve stem as you pump, it tends to wiggle back and forth repeatedly and can tear your brand new replacement inner tube at the stem base during the pumping process. That will cause most cyclists to utter an alternate word for "Oh pshaw!".

If we are going to show our pumps here's mine. I carry all that other stuff so it doesn't get lonely :)

I know that this is the Road Bike forum but mossi brought it up :D : If you are looking for a shock pump get a dedicated one. I got a pump from Specialized that was supposed to be for the shock and the wheels but it does neither well. After spending an hour trying to fix a flat on the trail about a mile from my car (I was GOING to fix it, dammit!), I flung it into the woods to be found by a future archeologist and went back to carrying a shock pump and a frame pump.

Is that Grizzly Peak above Berkeley?

My vote goes for the Zefal HPX (apparently they have some kind of new design out, according to the rivendell online catalogue that does both valves w/o flipping the widget). The only caveat that I can see is with the funny curving nature of joints on some carbon fiber bikes would make the spring loaded nature of it's mounting system rather useless.

What size is you pump and what's the length of your top tube? I have to buy one online, and I'm not sure if I should get teh medium or large. My top tube is 56cm. I'm thinking of putting pump under the top tube.
