What Shimano say...
Whether you’re looking to simplify the gearing on your adventure road bike, or you want to tear up some gravel routes, the tough and versatile GRX 810 model can handle it all. Ready for 1x and 2x speed drivetrains and available in various tooth counts, it’s designed to combine with larger cassettes at the rear to help you to maintain a smooth pedalling cadence over unpredictable terrain.
The 1 x chaining also adopts a “narrow/wide” tooth profile to prevent chain drops as you roll over the harshest surfaces. Made from lightweight aluminium, it adopts Shimano’s reliable HollowTech II system, bringing you increased rigidity for efficient power transfer.
