Apr 30, 2016 at 2:59 comment added Criggie @Rider_X Correct and accurate - I find the wind has a highly variable effect, and two or three times for each is probably insufficient data for a comparison. I have segments with 300 times, but the traffic lights make the data comparison less obvious. The two segments above are free of lights.
Apr 29, 2016 at 22:14 comment added Rider_X I am not surprised the large differences in average speed, especially on the flats as body position can have very large impact on your drag coefficient. You better be careful careful with these types of comparisons, before you know it you will start seriously looking at aero wheels, and slipstream kit for every advantage! Its a slippery slope.

Apr 29, 2016 at 22:05 comment added Criggie @Danielson the MTB had "combo" tyres, where the center was a long smooth bump all the way around the outside, and the shoulders had small blocks to the same height. So while riding straight ahead it was a slick, and while hard cornering it was a small block tyre. Pretend it was a road slick and you're close enough.
