I use this pump for bikes, cars and caravans. My bikes have three different valves, all are with this pump easy to operate. Surely you need an adapter for certain bicycle valves, but I need for all other pumps also. For Dunlop valves but no adapter is necessary. The pressure gauge is accurate. The pump makes a high quality, especially very stable impression. Even with more than 4bar handled very easily. The value for money is just great. No criticism of this Pumper from me. Therefore Conclusion: highly recommended
