Description

The SHIMANO FC-RX820-1 is a 1x gravel chainset designed to offer a balance of durability, low weight and mud clearance. Its design meets the demands of riding across mixed and varied terrain.

Compatible with 12-speed drivetrains, it allows you to pair a 10-45 or 10-51T cassette with several chainring sizes. The 40, 42, 44 or 46T configurations let you prioritise close gear steps or a wider gear range.

The chainset benefits from HOLLOWTECH II technology, combining stiffness, lightness and smooth rotation. Multiple crank lengths are available to tailor the setup to different body shapes and riding styles.
