Big Ring power vs. small ring power?
How does human physiology and performance compare when pedaling in the big ring versus pedaling in the small ring, when cog selection on the cassette makes the outputs similar?
Example
Big Ring 48T + cassette in 32T cog produces
Gear Ratio 1.50
Gain Ratio 2.99
Gear Inches 40.04
Development 3.19 meters
Speed 10.1 MPH
Small Ring 32T + cassette in 21T cog produces
Gear Ratio 1.52
Gain Ratio 3.04
Gear Inches 40.67
Development 3.25 meters
Speed 10.3 MPH,
Nearly identical.
But what is the physiological effect on fatigue, endurance, power and overall performance generally? If I climb a few miles in one versus the other, will I just plain be more worn out in one versus the other?
Is there a difference in the “power” (I don’t have a power meter!)
