But on the Crank Bros one there are handles to keep your fingers off the inflator.
for the record, on my main commuter bike I carry a lezyne pressure drive pump, and 1 co2 cartridge. But in ~3 years of commuting, I've only had 2 flats.
That is about my track record. A CO2 inflator sure is a lifesaver in the hot summer or cold -I have had flats in the summer with a hand pump and with a CO2 inflator and it is a big difference. I haven't used the Lezyne on my bike yet, but have used in a stranded cyclist.
