Review on 🚲 Durable SUNLITE Thorn Resistant Presta Valve Tubes in Various Sizes: A Reliable Choice for Your Bike by Jay Jeong

I have two of these fitted to my gravel bike. I have to say that I have never had a flat tire with these tires. This is unfortunately due to the fact that after about 5 hours of driving, only three trips, the valve stem area in the rear tire failed. I was about a mile from my third ride when the tire suddenly went flat. No warnings, just normal driving on a flat road for a second or two. The area around the valve stem has clearly separated from the pipe resulting in a very large unrecoverable leak. I've read reviews and seen a report of this bug, but I was hoping that with so many positive reviews, the bug was either batch related or rare. Now that I've opened up the tire it doesn't seem to be the case. This is clearly a design flaw. I've inspected the front tire and while it hasn't leaked yet, it's clear that it's about to fail as well. So if you already have them, replace them. If you haven't bought them, then don't. They will lead to more apartments they will save.
