I forgot to add that my 55 cm XO1 went through several iterations, including a "gofast" stage, at which point I got the weight down to about 20 lb IIRC. The Sun M14A wheelset and 190 gram 559X1" Turbo tires, plus the Topline Superlight triple and Speedplays, helped a great deal. No rack or fenders, of course.
The 38/24 X 13-27 drivetrain is on a 29er. Bump the rear cogs down by a tooth or 2 and you'd have the same for a 24-25" wheelset.
