Just thought I would pass along some results that my wife tested this week. I know everyone here realizes that a disc wheel is faster in almost all circumstances but for a very specific reason we needed to test this to verify to her team that she would in fact be faster with a disc wheel. The protocol was very simple. We live close to a 5 mile loop in which you almost never have to hit the brakes and allows for all yaw angles especially on windy days and in TX you can pretty much count on that. We used everything she would normally use in a race. Aero helmet, skinsuit, etc. Tires, pressure, enviromental factors were all controlled for due to the fact that all runs were within the same hour and nothing changed in that hour. If anything, the later runs with the 808 alone would have slightly elevated tire temps leading to decreased rolling resistance. The results were as follows:
808 with wheel cover for two 5 mile loops
average power for each loop 202
average time for each loop 12:11.5
808 only for three five mile loops
average power for each loop 205.3
average time for each loop 12:27.6
Range on the tests were +/- 3 watts and she held aero position the entire time on all 5 runs. To be honest that was a bigger difference than I expected. I expected it to be less than 10 seconds and when asked, she said she "felt" the 808 by itself was faster I think due to the fact that it has less rotational inertia but I could be wrong. The one amazing thing that stands out to me is that she can go 24.9 mph on 202 watts. Road condition is good but not great. Winds and temp on that day were 52-58F and 12-15 mph can't remember wind direction but it was consistent. Hope yall get something out of this and if you have any questions let me know.
