What are the key differences between a cyclocross bike and a road bike, and how does the design of a cyclocross bike as a road bike affect its performance on different terrains?

Cyclocross bikes are designed for off-road racing and have wider tires, more clearance for mud, and a more durable frame compared to road bikes. This design allows cyclocross bikes to handle rough terrain and obstacles better than road bikes. The differences in design make cyclocross bikes more versatile for various terrains, while road bikes are better suited for smooth pavement.
