What are the main differences between a cyclocross bike and a road bike, and how do these differences impact performance and versatility?

Cyclocross bikes are designed for off-road racing with features like wider tires, disc brakes, and more durable frames. Road bikes are built for speed on smooth pavement with lighter frames and narrower tires. These differences impact performance by making cyclocross bikes better for rough terrain and road bikes faster on pavement. Cyclocross bikes are more versatile for different terrains, while road bikes Excel on smooth roads.
