I have seen more flats then I care to count working in the cycling industry, but this is a first! What are the odds you would roll over a nail on a ride? If you have been riding in Austin, I would say pretty good. This nail clearly had the upper hand advantage and penetrated all the way through the DT RR 1.1. Needless to say, the Continental Gator Skin tire was no match for this framing nail.

Wow,that’s quite amazing. Did the front tire flip the nail into position to “nail” the rear? Did the rider manage to ride it to a safe stop? I hope all is well with you and yours.

Not sure what exactly happened. I like your hypothesis, though. The rider was able to come to a safe stop. It was not till the wheel made it to ProCycleWorks, that the rider realized the severity of damage. Thanks for reading!
