I bought this only for P to S conversion. the adaptor is smply too short, Decathlon's own mini pump cannot securely fill air. LOOK elsewhere
Thank you for taking the time to give us your feedback. The kit contains adapters to most kind of valves. It also contains the Presta and Schrader converters as well. The adapters work well in all our pumps. Please try inverting the valve in your mini pump and then give it a try. If you are still not able to use the product, you take take it to the store, ask for advice and if the products fails to perform, you can return/exchange.
