I wasn't there when the item arrived. I didn't know what a Presta valve was, but I had a bike pump with a two-pronged nozzle. One of the nozzles on the pump turns out to be a Presta. The Presta valve is what you find on a road tubular tire. This tube is suitable for commuter bike folding tires. I don't know what else to write but to hell with Amazon. Why should I explain what a Presta valve is to your next customer?
