TheShimano GRX 48T Chainring for FC-RX810-2, with its optimized tooth profile, ensures that GRX 2-speed chainrings keep the chain in place even in the toughest gears. When riding on the roughest trails, conventional road bike components quickly reach their limits on Gravel bikes. That’s why Shimano has developed its own drivetrains tailored to the special demands of rugged terrain for this type of bike.
The GRX chainrings, made of lightweight aluminum, are extremely sturdy and designed to increase torsional stiffness and thus durability against the forces involved. The climb assist features on the large chainring allow—as is typical of Shimano—a smooth, effortless climb and descent in any situation. To better meet the specific needs of Gravel riding, the refined shifting options with tighter gear ratios ensure a steady, fatigue-free pedaling rhythm.
