I used to carry two CO2 cartridges with dispenser, patch kit and spare tube. It served me well during rec. rides and my two flats in a years commute. Today I had a flat, bottle cap, damage tire. Repair tube, ride one mile, to find I missed a small leak, out comes the new tube (should have done from the beginning), and as I'm unscrewing the CO2 pump from the nipple, the stem valve comes out and deflate the tire. Stranded with no more options, walk to gas station and fill. Good thing it was on the last leg going home. Went to bike store and bought new tire and frame pump.
I filled the tire at home with new pump, took one minute to get it to 90psi, that's 30-40 sec. more than with the CO2 cartridge! I'm sticking with the good old pump, even if it weights more!
Also I have been thinking of carrying a spare foldable tire!? Do you carry one?
I'm just curious to see what other people carry as far as flat kit goes! Thanks! Double O
