Designed for riding on rough tracks, through gravel and mud, so that you can get wherever you want to go comfortably and stress-free and achieve the unique feeling of performance. The first component group developed by Shimano for gravel riding. Instead of telling gravel riders what they need, Shimano's developers asked them what they want. Shimano listened for two years and spent countless hours talking to gravel enthusiasts from all over the world. They rode on dust and gravel roads and narrow tracks, crossed streams and mountain passes to get an idea of what a Shimano gravel groupset could look like.
