Ok, thanks. I did an extensive search and even spoke with fellow cyclists with medical backgrounds, and there are no vascular surgeons in the Minneapolis/St. Paul area that deal with cyclists or specialize in the area of sports. I made an appointment with a surgeon, but there is absolutely no equipment to test after a ride (or even a run), so that's a dead-end. I would think there should be someone at the Mayo clinic, I just don't know how to find them. I saw someone posted Dr. Cherry's email-wondering if that's still current? If so, I can email to see if there's anyone local.

***Googled Dr. Lee and emailed-thanks! I hope there's someone local. Maybe I can do the test with my own bike, which is still in the aero setup***
