ROTOR Round Ring BCD110x4 31(48) SHIMANO® GRX Inner. Shimano® took an early lead in the gravel category when it introduced its dedicated GRX groupset for gravel.
Not one to follow, ROTOR quickly caught up with compatible 48/31 and 46/30 Q RINGS combinations with BCD 110/80x4 for Shimano® GRX cranks.
If you want to improve your performance and pedal in a healthy way, these chainrings should be your choice.
