ALUGEAR Aero GRX 2x Chainrings for Shimano RX810/RX820
The ALUGEAR Aero GRX 2x Chainrings for Shimano RX810/RX820 are compatible with Shimano 8-series GRX cranksets. These chainrings match the 110/80 BCD 4-bolt pattern and eliminate any gaps between the crank arm and chainring. This provides aero advantages as well as a clean look.
These ALUGEAR 2x GRX chainrings are CNC machined from 7075 T6 aluminum and anodized to provide protection from impacts. This makes them durable and reliable in even the toughest off-road conditions. ALUGEAR chainrings also use a unique tooth profile that eliminates chain noise, reduces wear and provides a more efficient drivetrain.
