Last month, for the first time in thousands of KM, I got a flat tire.
It was fixed (replaced tube) and I've happily ridden another 400km since.
But I ride at nearly max pressure for the tires, because I assume this was caused by a pinch flat. At the time this flat happened, I was not running low pressure, but lower pressure than I am now (50psi vs 60psi, perhaps), and it happened on a very low speed ride on a smooth trail... no hard hits.
This was a new tube that I installed about 350km earlier, so maybe "user error."
But can someone tell me what might have actually been the cause of that type of flat?
That definitely looks like a pinch flat. Did you do some hard cornering that could have folded it over? Or maybe a jump?
Edit: after looking at it again, I wonder if it's a defective tire. Take it back to the bike shop and ask for a refund.
Defective TIRE? I've had those tires on two bikes, maybe 1500km of riding before that flat. The tubes were "new" (350km-ish).
Did I say tire? I meant inner tube. It almost looks like the rubber separated.
Could be. I've never had this happen, and these were Schwalbe tubes (I've only ever had no-name tubes before. LOL).
This is a good excuse to just go tubeless. The only drawback is that they'll go flat faster from lack of use. Just ride often, or be ready to pump them up before you go riding.
Edit: okay, that's not the "only" drawback, but I've been really happy with my tubeless setup. It's probably not a great idea if you live in California, or other areas with dry dirt and lots of stickers, but it's perfect for the PNW, the South, and other wet areas.
I've got tubeless tires on my e-scooter(s), and it's nice. But I'm not ready to invest in new wheels, new tires, etc. considering I've been perfectly happy with my tube/tires for many thousands of KM.
Not to say that tubeless isn't in my future, eventually. I'm just not ready to go there any time soon 😄
Oh, yeah if you'd need new wheels then it's probably not worth it. I just got a new bike a few months ago (Cannondale Habit 4), and it came tubeless ready, so I had the shop set me up tubeless. It's pretty rad because I can lower the tire pressure pretty low for slippery stuff and not worry about pinching a tube. It's also a little lighter, although that doesn't matter much considering what a FS mountain bike weighs these days. Welp, good luck avoiding flats in the future! I still say that looks like it might be a tube defect. If you have the time then it might be worth taking it back to where you bought it and asking for a replacement.
