I bought a set of Ultegra/Open Pro wheels because I have an older bike that would look silly with the latest crop of low spoke count wheels. It helped that I got a spankin' good deal on the Ultegra/Open Pros as well.
I have about 30 miles on them and have had to touch up both wheels. It may be my fault, I'm a new to road bikes and skinny tires. I need to learn how to avoid pot holes. Since I touched them up the first time, they've been fine.
