Nano Fumpa pump #schrader then you love it becauseThis pump is for the roadies tiny, pocket sized, light, powerful, simple, reliable and no nonsense. A Nano is like carrying a couple of CO2 cartridges in your pocket for Justin: 'just in case'. But with more capacity than two CO2 cartridges and fully reusable because it's rechargeable. A Nano will inflate road or gravel tyres from fully flat to rideable in 50 seconds. That will give you around 65 psi in a 700 x 25c tyre or 20 psi in a chunky 29" x 2.
