Features

Shimano GRX

Shimano GRX was designed from the ground up for gravel adventure. With its gravel-specific ergonomics, optimized gearing options, rugged reliability, and quiet, stable drivetrain, GRX sets itself apart from the rest of the component world.

Shadow RD+

Shimano's Shadow RD+ technology uses an adjustable rear derailleur clutch to reduce chain slap over rough terrain. This simple chain drop solution is lighter and more efficient than roller bearing chain management devices.
