While powering through a light this morning I ate $hit. But something isn't right. I was just powering through when it seemed like my rear wheel lost traction and then locked up. While my head was traveling towards the asphalt it went through my mind that I threw a chain. It sure seemed like I threw a chain. But as I collected myself and came to my feet I realized the chain was still connected and tension was right about perfect. What the fu¢k?
I was going perfectly straight on a flat road with a good road surface. A trip back to the seen shows no signs of oil, leaves, plastic or anything else that would have led me to lose traction. It was a dry day no water on the road.
My bike set-up is a Peugeot team (reynolds 531) convert with Miche hubs, 18t rear, 52 tooth front mounted to an Apex 5 RG crank. The bike has Armadillo tires. The chain line is really good.
The bike seems ok, I just needed to straighten and re-tighten my stem and re-tape my bars.

So what the fu¢k happened? Any ideas?
