At least that's what they tell me they're spinning when they beat me and I ask them about it. I'll try to get some video and post it, it's pretty wild to watch.
It's a guess but its pretty good one. The kid was 16 so he's on a 86" max? He rode a 12.2 f200 and I calculated his average cadence of 156 so I'd guess he hit the 200 line around 160? Then he came around me in a sprint and I was in a 104 at 61kkph spinning 125. This time of year I'm nowhere near riding my biggest gears so he might of been on something smaller?
I just did the math.
gear: 48/15 = 86.4" or 6.72m or 3.20 ratio
rollout: 6.715m
distance: 200m
target time: 12.2"
avg cadence: 146RPM
avg speed: 36.6mph / 58.8kph / 16.3mps
