In the mid-2010s, a new riding style called gravel riding became popular in the Midwest of the United States, and it has taken off worldwide. Riders enjoy long-distance cycling along gravel and unpaved roads. In response, Shimano developed SHIMANO GRX as a components series for gravel/adventure bikes in 2019. Utilizing the technologies and expertise that Shimano had long cultivated, it developed components specific for gravel riding. GRX features specially designed hoods and shift levers and multiple handlebar position brake levers suitable for off-road long-distance cycling, disc brakes, high operability, a wide gear range, robustness, and more. It was designed so that riders can cycle comfortably and stably whether on rough roads, mountain tracks or paved roads. Shimano offers a broad lineup of products for riders who enjoy a wide variety of riding styles and wish to customize their bicycles and components in response to different types of terrain. Gravel riding is attracting great attention, and is a riding style that is going to further expand in the future.
