XLAB's Tire Mate is a combined CO2 inflator and mini pump for complete peace of mind. It's so small that it fits into the smallest of our XLAB bags (sold separately) and it ensures that if you run out of CO2 cartridges you can still pump your tires up to 90 psi. When used as a CO2 pump, you can regulate how much pressure you put in your tires, too. This fine mini is built of CNC-machined aluminum for lightness and reliability. It has high-tech seals throughout, fits all valve types and even has a magnet to keep the pump closed when you're carrying it.
