This pump has come to replace the CO2 cartridges that normally adorn my rear pockets. A good move because this baby is super light. At a claimed weight of only 58g, it feels more like a pencil then a pump against my back. After using it for about two months I can say it does take a little while to actually fill up a tire, but well worth the extra weight you do not have to carry around. Blackburn says the max pressure is 160 psi/11 bar. Overall it gets a huge thumbs up for its simple design and compact size.
