Here's an interesting observation.
I've been swapping and changing the gearing on my commute bike.
As a test, I ride round the 50 km loop which is home to the Birmingham Outer Circle, once round clockwise and return to home.
I record the ride on my Garmin 605. I post process the data to find my average speed for 0% gradient +/- 1% for speeds OVER 10 mph.
On 46 x 24, the speed is 14.1. Change to 46 x 20 and the speed increases to 14.2. Change to 46 x 22 and what speed do I get? Yup, 14.15. How about that.
Now I need to find out what gearing gives me the fastest speed before the gearing is too high to pedal.
Or plot a curve to see where it goes non-linear, indicating I've reached my 'sweet spot'.
