Be ready for anything with the Air Rush Elite CO₂ Inflater. It can easily be stowed away in a pocket or bag and is compatible with both Presta and Schrader valves, so you can quickly inflate your road, city or mountain bike tyres when you're in a bind. A spring-loaded locking mechanism makes inflation easy, and a rubber sleeve on the CO₂ cartridge keeps your hands comfortable during use.
When using with a Schrader valve, it works best to grasp the tyre and rim with both hands and use your thumbs to push inwards at the valve. This ensures you don't push the valve back into the rim with the inflator and will allow air to flow into the tube best. Don't be afraid to push hard or have a friend help you here!
