WOW, John. You probably saved me a few nights in the hospital. First thing I need to do is to install a longer stem, which will bring my weight a little bit more forward. My 61cm Trek has a 120mm stem. This 59cm Kestrel only has a 110mm stem. I was thinking while riding that I feel I was "cramped" and not stretched out enough and needed to either push the seat back a bit or get a longer stem so I can "reach out" a bit more. Thanks again for your help. The cyclingtipsblog and a referenced velo news article told me everything I need to know in avoiding high-speed wobble in the future.
