It's somewhat ironic that since I built up a dedicated commuting/touring bike over the winter, I've been reaching for my "roadiest" bike for most of my commuting:
It has the most aggressive/aero positioning of all my bikes, and the gearing has changed from the original 48/38/28 triple with 12-28 cassette to a 50/39 double with 13-23 cassette. The original saddle broke, and gave way to a B17S (too wide) to a Brooks Pro (too round) to a B17N (just right.) Since this picture was taken, I've also changed to SPD pedals. It's fun.
