SHIMANO GRX FC-RX610-1 12-Speed Single Crankset

The SHIMANO GRX FC-RX610-1 12-Speed Single Crankset balances lightness and optimised efficiency thanks to a range of gearing options suited to the demands of mixed gravel riding.

Thanks to HOLLOWTECH II technology, its hollow crank arms offer an excellent stiffness-to-weight ratio. Paired with a 10-45T or 10-51T cassette, it allows a choice between close gear ratios (38T) or an extended range (40T), depending on requirements.

With its 49.7 mm chainline and asymmetric 110 mm BCD, it is compatible with 135/142 mm road disc hubs, for gravel, cyclocross and bikepacking use.
