I am aware of that, but to me mounting pumps beside bottle cages also looks bad and gets in the way. I realize that aesthetics sometimes have to give way to functionality, but I don't understand why we can't have both when it comes to pumps. BTW, I also carry a CO2 cartridge in my seat bag and generally use that as the first choice when fixing flats. However, I also carry a pump in case I get more than one flat and run out of CO2, having learned that lesson the hard way.
