The number of teeth on a sprocket impacts torque and power in bike drivetrains at different speeds. Fewer teeth increase rear wheel torque at low speeds, aiding acceleration and power transfer. Higher speeds and aerodynamic drag diminish the sprocket's effect, leading to a need for balancing pedaling effort, efficiency, and maintaining cadence. Multiple factors influence torque and power output, requiring experimentation for optimal performance.
