One of my bikes has a triangular top tube that doesn't lend itself to mounting a Road Morph. On that bike I've got it on the bottom side of my down tube, with the Topeak mount secured with zip ties at one end, and just because I hate rattling noises(not to mention falling pumps) I've got one of the aftermarket rubber block/Velcro strap mounts at the other. Since I'm 6'2" 235# I have the luxury of not worrying about the few extra grams the second mount adds.
