Shimano GRX RD-RX820, derailleur, 12-wheel, long strap
Gravel cycling has its roots in simplicity, inclusiveness and curiosity. Everyone from beginners to grizzled veterans rely on Shimano GRX, the first gravel-specific set - for smooth shifting, reliable braking and exceptional off-road comfort.
Shimano GRX sets itself apart from the rest of the world of Shimano parts, and the new RX820 range offers premium performance at an incredible price, with thoughtful ergonomic design and gearing focused on gravel roads.
This is not an elaborate set of road components. It represents a fundamental view of how cyclists want to explore their world.
Shimano GRX helps you eliminate excuses, instead encouraging you to try a rough side road or last a little longer in the saddle.
