Saw a cyclist today standing outside of the garage with a thousand yard stare…. Asked him what was wrong and he gestured at his rear tire. It was off the bead with sealant coating the back of his bike. I asked him if he wanted a spare tube to get him going again. And he told me that he had a spare tube but that the bike shop had done the locking ring up on the valve so tight he couldn’t get it off. Of course I offered to help and he was absolutely right without a pair of pliers it was not coming off
Eventually his taxi came and he went. But the moral of this story is to check your locking rings on your valves to verify. You can actually undo them by hand – or carry a pair of pliers!
Poor guy, apparently the failure had happened 40 minutes into a 3-hour ride
