Connects to all types of valve (Presta, Schrader, Dunlop) by clipping the universal head on.
How to use your pump
1) Select the correct connector for your inner tube's valve (by inverting part of the head. See diagram in the product photos).
2) Push the pump onto the valve.
3) Use the blue lever to clip the pump into place.
4) Inflate to the desired pressure.
Had to visit the internet to figure out how to switch the valve nozzle, but otherwise easy to use (there might have been instructions on the packaging but I threw that away weeks before I actually needed to actually use the pump) . For the price I couldn’t ask for more!
