Why do you have to stow the pump? why not use the bottle cage bracket and mount it there?

Where are you stowing the pump? in you jersey pocket? I knew a guy who did that, had a crash, and that pump destroyed a disk in his back when he landed on it.

There is a new mini pump that I hadn't seen before, Topeak makes it, it's called the ROADIE TT Mini, TT stands for twin turbo, obviously there are no turbos inside of it. But if used correctly you can pretty effortlessly get to 90 psi, but it will take a god awful amount of strokes. Made only for presta, it is a two stage pump and it has an end cap that you turn to get it from high volume to high pressure, so you start pumping in high volume mode, then when it gets tough switch to high pressure, when pumping this thing you have to remember not to put your palm covering the back end cap because that's where the air sucks into the pump from. It's 6 1/2 inches long weighs 90 grams. It is a direct connect pump so you have to be careful when using it that you don't "saw" the valve back and forth as you put air into the tire, but from a video I saw of a guy using just two fingers to get the pump to work you shouldn't even be close to straining that might cause a person to start sawing as their pumping. This pump has pique my interest, and I think I will get it. It cost $44. There are not a lot of videos on that pump yet, one lady hated it, but I think she didn't know how to use it, because another video the guy liked it and was using just 2 fingers to stroke to pump with so we could see how little effort it took, she said it was killing her to get to 60, so I think she didn't change over to high pressure mode.
Stowage is in a seat bag. Exposed pump stowage is not an option for my use.
