I am still fighting this fear after almost 8 years. I feel totally unstable descending in the drops. I finally started using the drops on the flats, in headwinds, etc last year. Yesterday, I went to the LBS and read them the riot act. I had shims put in my brakes at the beginning of the season, but it still feels like the reach is too far. So I am getting a shorter stem and if that doesn't work, he will take the bike back (after 2 years, so that's a pretty good deal). It helped that I had my pro racer "adopted" son with me when I went in. The owner gave me all of the stupid arguments against going back to a smaller, 650 cc wheel bike, which thanks to everyone here, I could refute. I do love my bike and its lightness, but it is basically too big for me. I know I have some basic wimpiness and fear about descending in the drops, so I am hoping between the shorter stem and some courage I can cure myself of this problem!
