Review on 🚲 Presta to Schrader Tube Pump Tool Converter Adapter for Bicycle Bike Tire Valve - Pack of 5 pcs/Bag by Jaymai Alford

Since I have Presta valves and a Schrader pump and an air compressor I needed this adapter. They fit and work great, but there's a problem. You need to remove the adapter, open the Presta, and then screw the Schrader adapter back on. Then apply air, then remove adapter, close presta valve and put on schrader adapter with dust cap. I tried leaving the presta valve open with the adapter plugged in and air leaked out. Overall it works great but added a bit of time to pump up the tires. You need Schrader dust caps.
