Review on 🚴 Innolife Aluminum Presta to Schrader Converter: Versatile Car Valve Adapter for Bicycle Bike Tube Pump, Air Compressor Tools by Wesley Bell

I ordered these because I accidentally ordered Presta valve chambers for my everyday commuter bike. I was hoping this would be the perfect way to use all of my existing air and gas station pumps with them as adapters. They work, but be aware that not all air pumps work well with them. The internal pin that opens the valve poses some problems with some air pumps. You may have to move a little to let air in, but they work for me.
