I’ve swapped 3 bicycle Presta wheel sets and 4 Schrader valves over. So far - flawless. So easy to use day to day and zero leaks.
Clicks in place and stays in place until I remove it. It's not seated perfectly with the air hose valve into which it's threaded and the result is leakage at higher pressures. Today I struggled to inflation two tires past 70 psi due to this leakage. Works perfect at MTB tire pressures, but iffy for road pressure.
These work amazingly well. Super easy to connect/disconnect with no air loss.
They work as advertised, are very premium, and they have the little tool on the end so you don’t need to carry around the tiny tool the comes with the valves.
Easy to install. More sturdy than presta valves. Simple conversion to the equipment you already own.
