SUMMARY
The discussion clarifies that bicycle gear ratios are calculated using the formula gear ratio = rfront/rear, where rfront is the diameter of the front gear and rear is the diameter of the selected rear cog. A change in gear ratio from 4 to 0.7 indicates a significant difference in the diameters of the gears being used. The rear wheel features a "rosetta" with 7 cog wheels of varying diameters, while the front setup consists of two gears. Understanding these ratios is crucial for optimizing pedaling efficiency and speed.
