Bike + rider weight: 91.7 +/- 0.5kg

Ergomo Power meter
Stabilised at ambient temperature for 25 min before offset
Offset calibrated before test: 983 offset value
Offset calibrated after test: 983 offset value (no change)

Description:

Ride at constant power and speed for 2-3 laps of the velodrome
Choose range of speeds from 25 to max capable KMH eg.
25, 28, 30, 34, 38, 40, 42, 44, max.

Ride on blue line of track (ie same distance up the bank) to prevent changes in potential energy.

Change aero equipment and repeat test using same protocol above.

Download power file, isolate sections of speed with same initial and final speed > 60 seconds in duration, calculate average watts in this section of data.

Plot data using fancy spreadsheet (Coming soon).

Results:

What? You want results? Just kidding - working on these right now and will post when completed (soon).
