For your riding freedom: the GRX RX820/610 2x12-speed disc groupset from Shimano
Finally, for more price-sensitive customers and to enable a wider price range for complete gravel bikes, Shimano has updated its 600 series cranks and shifters for 1x12 and 2x12 setups, which now utilise the technology of the original 800 GRX component line as a result of a trickle-down process.
Key features include textured covers and a non-slip coating on the brake levers to improve control over rough terrain. The new cranksets offer gearing options specifically designed to meet the demands of gravel riding. The 2x12 crankset is equipped with a 46 mm and a 30 mm chainring and is available in crank arm lengths of 165, 170, 172.5 and 175 mm. The RX610 1x12 crank has the same four crank arm lengths and is now available with a heavy-duty 38T or the traditional 40T chainring. These options are combined with a 10-45 or 10-51 cassette.
