Fanttik X10 Ace Mini
Recommended by Syd and Macky
We've started carrying the Fanttik X10 Ace Mini air compressor during races instead of a second CO2 cartridge. It's only 35 grams heavier and will inflate up to three 29" tires on a charge (unlike a CO2 which is only good for 1 tire). And for rides, we skip the CO2 altogether and just carry this.
