[QUOTE=_ForceD_;21106902]After four decades of cycling I just very recently got brave enough to go with a CO2 inflater, and find myself leaving the pump at home. This thanks to the urging of other CO2-using forumites. Maybe he could fashion a frame-mounted CO2 cartridge holder for you.

although I dislike CO2 cartridges, they generate waste and when you run out you are stuck, unlike a pump which has an unlimited supply. Plus you get some exercise using them.
