ROTOR Round Inner Rings Shimano GRX BCD110/80X4
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 Round Rings combinations with BCD 110/80×4 for Shimano® GRX and ROTOR BCD110/80×4 cranks.
