Review on 🚲 Bike Bits Brass Presta Valve Adapter - Easily Convert Presta to Schrader and Inflate Tires with Standard Pump or Air Compressor (4 Pack) by Joseph Campbell

It was a bit difficult to get them to work but I think it was more my fault than the product. I had to loosen the Presta valves before putting on the Schrader adapters. Somehow I couldn't inflate the tires with air even with loose Presta valves and the Schrader adapters. After double checking the description online, I tried the adapters again and everything worked fine. This is a great idea and I would recommend it to anyone who has Presta valves but only Schrader inflators.
