What are the key differences in endurance vs road bikes and how do these differences impact performance and comfort during long-distance rides?

Endurance bikes are designed for comfort over long distances, with a more relaxed riding position and wider tires for stability. Road bikes are built for speed and efficiency, with a more aggressive riding position and narrower tires for reduced rolling resistance. The differences impact performance by affecting aerodynamics and power transfer, with endurance bikes being more comfortable but slower, while road bikes are faster but less comfortable on long rides.
