Finally, for more budget conscious consumers and to allow a wider price range on complete gravel bikes, Shimano has updated its 600-series cranks and shift levers for 1×12 and 2×12 setups that utilize trickle-down technology from the original 800 series GRX component line.

From the beginning, riders have counted on Shimano GRX for the smoothest shifting, most reliable braking, and ultimate gravel comfort with thoughtful ergonomic designs and gravel-centric gearing. Now, with the updated 12-speed mechanical GRX lineup, you get more. More options, more gears, more opportunities to get out and ride exactly the way you want to ride. No matter which Shimano GRX option you choose, you’ll have the right gear—and gearing—for your next off-road adventure.
