These were the so-called thorn resistant ones. 👍 Normally very decent, hence me only carrying one spare.
That second flat this morning was weird. I picked up a sewing needle, which "normally" would have been easy to patch both holes. But since I was going somewheres around 30-40 mph, it took some time to stop. In that time, the valve stem area got pretty mangled, from me braking so hard while the bike wanted to keep going. That'll get your heart pumping, lol. 😁
