Shimano GRX RX815 Di2 Gravel Groupset - 2x11 Speed

Shimano GRX, with its gravel specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world. It isn’t a reworked set of road components made for all-terrain riding, this groupset represents a ground up look at how cyclists want to explore their world. Shimano GRX helps you eliminate excuses, instead urging you to try that rough sidetrack or ride that little bit longer. It offers you the option to Explore Beyond.
