I'm currently in the process of building one of these. I bought the Large, biggest size they make. 57cm seat tube, 58.4 top tube, fairly similar to my current road bike so it should fit pretty well. I'm amazed at how small a frame set looks without all the bits on it.
I'm considering some wheels made by Psimet for training and entry level racing with Velocity Deep V's, Dura-Ace cranks, and a Deda stem and Deda pista bars.
