FBC 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

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

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

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.

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

Muy útil y necesario, y ademas los vídeos podrán y las imágenes tambien ser del agrado de todos, pero la realidad es que los comentarios pesan más

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.

I bought these and they fit the valve well enough but damned if I can get them to work. I went first thing to my local filling station and couldn't for the life of me get air in the tires...
