Review on Presta 19 23C Bicycle Valve（2 Patches by Eric Temple

You really pay for what you get. Again and again she told us that it is important to listen to your inner instincts. I figured I'd be a little more conservative with my money, which isn't worth saving. I had a flat tire within a week, the tire is fine, the tube burst for some reason, I can't find anything in the tire. I have another tire with air for some reason, when I pumped it up the stem came loose. Now both teams are bad and I bought these less than a month ago. Just do yourself a favor and don't buy them.
