I think I'm going to start leaving my pump behind for commuting since I go less than 4 miles. (I'll save it for the weekend rides, one less thing to have to take off my bike.) I'd like to stick a CO2 inflation system into my seat bag however so I'll have something available. Nashbar didn't have a lot of selection. I found these however:
Pedro's Ego Inflator Pro
Pedro's Ego Inflator Sport
Planet Bike Air Ship
They all take either 12g or 16g (threaded/unthreaded). I can't tell from the photos how big these things really are but I'm looking to put the inflator and 2 CO2 cartridges into a
Novara Small Seat Wedge Bag (along with an Topeak Alien II, patch kit and spare tube).
Anyone have experiences with any of these systems?
