What are the main differences between GRX and Tiagra components for cycling?

The main differences between GRX and Tiagra components for cycling are in their intended use and design. GRX components are specifically designed for gravel and adventure cycling, with features like wider gear range and improved chain retention. Tiagra components, on the other hand, are more suited for road cycling, with a narrower gear range and less emphasis on durability for off-road conditions.
