Shimano Ultegra RX
Best reliable shifting for demanding off road cycling.
This component brings essential chain-retention technology to road and gravel bikes. By adding a clutch to the rear derailleur, it effectively silences the drivetrain and prevents dropped chains on rough terrain without sacrificing the crisp shifting performance expected from the series.
