Finally, to cater for price-conscious customers and to enable a wider price range for complete gravel bikes, Shimano has updated its 600 Series cranksets and shift levers for 1x12 and 2x12 set-ups, which now utilise the technology of the original 800 Series GRX component line as a result of a ‘trickle-down’ process, incorporate the technology of the original 800-series GRX component range.
Key features include the textured covers and the non-slip coating on the brake levers, which improve control on rough terrain. The new cranksets offer gearing options specifically tailored to the demands of gravel riding. The 2x12 crankset is fitted with a 46T and a 30T chainring and is available in crank arm lengths of 165, 170, 172.5 and 175 mm.

These options are paired with a 10–45 or 10–51 cassette.
