Presta Valve Adapter Converter for Standard Pumps to inflate Presta Valve Tubes and Tubeless Tires

These worked perfect. My front bicycle wheel got stolen, and I decided not to bring it to a shop and replace it myself. Had no idea that the air valve systems could be different (lesson learned), and unknowingly bought a tube that had a presta valve. These preseta to schrader adapters worked perfectly fine for me. There were cheaper alternatives, but I didn't need a 10 pack, and wanted it to arrive quickly via prime shipping (which they did, within a few days).One thing to note: if you plan to leave these on your presta valves, as I did, they don't come with caps. I picked up a small pack of them for a few dollars here: http://www.amazon.com/gp/product/B000KKLLFS

Small enough to go in my under the seat saddle and have for emergencies. Great items!

Simple solutions to fit regular pump. Nice and easy solution to convert Presta connection to use with schrader pump.

Worked fine on my bike tires. Easy/cheap solution instead of having to buy a new pump.

Worked exactly as it should. I carry one with me whenever I ride so I can access standard bike pumps. Very convenient.

They were fine quality but they were too short. They blocked off the intake so I couldn't actually pump up the tires. I tried shortening and lengthening the valve as much as possible to try and make it work. I couldn't. The adapter needs to be longer.

Product works. It fit the continental presta valve tube I purchased from Amazon. I realized I had to loosen the presta valve first then install the adapter.

Yeah they did the trick fine, I gave it only 4 because of being unhappy with a variety stem sizes. I know that's on me for not having my eyes open and I should have known. Presta Adapter's worked fine, it's just that I get tired of buying extra parts when I'm not paying attention out here. Word of advice, "always have your eyes open and never assume anything". Thanks p.s. I did say that was my fault, don't assume anything
