Considering the impact of crank length on a road bikes overall handling, how does the relationship between crank length and leverage influence steering control, particularly when cornering or navigating technical descents? Does a shorter crank length, which is often associated with improved leverage, necessarily result in more responsive steering, or are there other factors at play that could potentially offset this benefit? Furthermore, how do variations in crank length affect the balance of power output and steering control, and are there specific crank lengths that are better suited to certain riding styles or terrain types? Additionally, what role does the interaction between crank length, bottom bracket height, and wheelbase play in determining a road bikes overall steering behavior, and are there any potential drawbacks to prioritizing leverage over other factors when selecting a crank length?
