25c Pasela TG on a 20h A23 (matching rear soon). Built with Sapim Lasers to a Reynolds branded DT Swiss 240s. ~1400 miles so far, and it's needed one true since being built. Pretty good ride quality. Kind of flexy in the drilling I chose, but I can handle it. I want to move down to 23c's next time, though, 'cuz 25c's end up being huge on a 23mm wide rim.
