It's always interesting to read other peoples' experience of bike kit. I'm in the process of looking for a flat bar road or hybrid bike and have tried out a few with disk brakes, although not this type. I also have disk brakes on my Kona mtb. I agree that in most cases they do provide more, and probably more consistent stopping power, but to me they do not give the extra benefits over V-brakes on a road bike that would make me pay the extra money, or add the extra weight. No criticism of disks, just personal choice.

I can build wheels so the problem of changing rims is not a significant issue. As a side matter I've never had to change rims on any of my bikes because of wear, and I have some wheels that are 20 years old - but I regularly check them and my brake blocks. Perhaps that's because I'm a tinkerer and hoarder and am always changing wheels and other parts around on my bikes.
