I just received my confirmation letter. I am really baffled. How can you change the rules concerning the frame styles at this last moment. There was nothing in the original rules stating that Time Trial Frames, or Aerobars, could not be used in the time trials. Time Trials, and Road Racing, are 2 different genres of cycling. Both require frame styles to accommodate each event. I am totally blown away, as I am sure other TT athletes are.
