I built a set of M13-II's to replace the 23mm (external) rims on my Hybrid, since I was running skinny (26mm) tires.
Maybe that's not the trend, but I'm more than happy with my decision. I'm pretty sure I wouldn't have done a 70 mile day on my old rims. Previous best with the old rims was 50 miles 2 years ago, when I was a mere 63!
