I've had GEL 280s, Ambrosio Cronos, and Fiamme Yellows and Ergals since the late 70s, my racing days. I rarely weigh over 150 lbs and "ride light" so I've had really good luck with them. In more recent years I've built even lighter wheels including a couple pairs of 24h and one pair of vintage 20h (Scheeren Weltmeisters). This was pure dumb luck to crash the Mavic yesterday. I was distracted by something off the road and when I looked back there were the potholes. The winter wasn't harsh here but it was very wet at times and it's taken a toll on some roads.
