The Rixen & Kaul Pumpfix is a very handy little widget that provides you with a way to carry a full-size pump if your frame doesn't have a place for one. It's tidy, and simple to fit.
If you want to get a flat tyre back up to full pressure quickly, you have two choices. You can dump in one or more CO2 cartridges, adding to the world's supply of empty gas canisters and costing you money, or you can use a full-size pump.
Problem is, carrying a full-size pump is hard on many modern frames, especially if you also want to carry two water bottles. Your typical frame fit pump is designed to sit alongside the seat tube, but putting it there covers a pair of bottle bosses. Many frames, especially compact layout designs in carbon fibre, don't have much room there anyway, or have sweeping curves that stop a frame fit pump from wedging into place.
What you need is a pump clip, and the Pumpfix is the tidiest I've seen. It has an 'endless band' design, with the ends hidden in the body of the clip. It'll fit round frame tubes from 15mm to 60mm across, and irregular ones with equivalent girth.
To get a tidy result, you have to trim the band, very much 'measure twice, cut once'. Not being that skilled, I got it about right, assembled it to see how much excess band there was, then took it apart again, trimmed the band and finally clamped it into place. That last step's just a matter of tightening the bolt that pulls the end of the band into the body.
With the Pumpfix in place at the front end of the top tube, my trusty Zefal HPX jams firmly into the seat tube junction. The Pumpfix sits solidly, and the pump stays where it's supposed to be.
Nifty widget that does its one job very well

Our official grumpy Northerner, John has been riding bikes for over 30 years since discovering as an uncoordinated teen that a sport could be fun if it didn't require you to catch a ball or get in the way of a hulking prop forward.
Road touring was followed by mountain biking and a career racing in the mud that was as brief as it was unsuccessful.
Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work. He's pretty certain he's worked for even more bike publications than Mat Brett.
The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.
