7 12 2009 flying 200 meter gear and line experimentation

I decided to do some experimentation today based on the results here. What I did for the five flying 200 meter efforts below was to under gear myself (81"), use a normal gear (90") and then over gear myself (96" & 108"). I also used a different line than my normal line for all efforts. The results were pleasantly surprising.

The weather today at around noon was:
Temp - 81F
Humidity - 26%
Wind - 15 mph NW
Pressure - 29.86

1st effort:
- 48 x 16 = 81" Gear
- Time = 13.28 seconds
- Max cadence = 146 rpm
- Average speed = 33.6 mph

2nd effort:
- 50 x 15 = 90" Gear
- Time = 13.00 seconds
- Max cadence = 134 rpm
- Average speed = 34.4 mph

3rd effort:
- 52 x 13 = 108" Gear
- Time = 12.69 seconds
- Max cadence = 116 rpm
- Average speed = 35.22 mph

4th effort:
- 52 x 13 = 108" Gear
- Time = 12.55 seconds (12.56, 12.62, 12.47)
- Max cadence = 119 rpm
- Average speed = 35.5 mph

5th effort:
- 50 x 14 = 96" Gear
- Time = 12.73 seconds (12.72, 12.74, 12.90)
- Max cadence = 128 rpm
- Average speed = 35.2 mph

The times for all five efforts were personal best times, and I think I have finally found the key to riding consistent flying 200 meter times below 13 seconds. To get the times on efforts 4 & 5 there were three stop watches being held by three different people to keep the timing honest.
