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.
Precise and clean wireless shifting with Integrated on-board removable battery (BT-DN320 sold separately).

- 13T solid pulleys and decreased derailleur tension prevent high chain tension in low gears
