I bought this tube and it only lasted about 3 months on my bike. I didn't do anything crazy, I went up a small 4 inch curb and it popped the tube. Now I need to order another one. I have fat tires on my 26-in e-bike and I've had bad luck with these. Both the factory originally equipment to and the aftermarket that I ordered from sgv bicycles did not last very long all. We'll see what happens with the next one. Maybe I need to order better tires.
