Shimano GRX FC-RX820-2 Chainring 12s Black

SHIMANO GRX FC-RX820-2 INNER CHAINRING 31T 12s BLACK

The 31-tooth Shimano GRX inner chainring is a genuine replacement part for FC-RX820-2 12-speed double cranksets. It is designed to work together with the 48-tooth GRX outer chainring, forming the original 48-31T combination developed by Shimano for 2x12 Gravel drivetrains.

Its aluminum construction provides high stiffness and strength while maintaining a low weight. The 80 mm bolt circle diameter and its specific design help preserve the original shifting quality and precision of the GRX crankset.

The 48-31T combination provides a wide gear range, offering suitable gears for both high-speed riding and tackling steep climbs and demanding Gravel terrain.
