If you want to save yourself some time and energy when you’re fixing punctures on the side of the road or trail, the CO2 systems will get your tyres reinflated quickly and easily. Particularly useful for road bikes, where reaching the higher pressures required can be challenging with a hand pump.
The Lezyne Twin Speed Drive works with both valve types, and will release the whole cartridge in one hit. If you want to control the CO2 release, perhaps just to top up the tyre after using a hand pump, go for either the Bontrager Air Rush or Lezyne Trigger Speed Drive.
You’ll still need to carry all your puncture tools, and a hand pump in case you’re having a bad puncture day and run out of CO2, so if you need that too, go for one of the kit options.
Unconditional Bontrager Guarantee - all Bontrager pumps come with a 30-day trial period, if you don’t like it, return it for a no-quibble refund.
