Shimano has expanded its GRX gravel groupset with new crank arm lengths and larger chainring options, enhancing performance and adaptability for gravel riders.
Larger Chainrings
The addition of 44T and 46T chainrings complements the existing 40T and 42T options, providing riders with higher gearing suitable for flat terrains and competitive events. These larger chainrings maintain Shimano’s commitment to a smooth and efficient drivetrain experience. (bikepacking.com)
Shorter Crank Arms
Shimano now offers 160mm and 165mm crank arm lengths alongside the standard 170mm, 172.5mm, and 175mm options. Shorter cranks can improve aerodynamics, reduce knee and hip strain, and facilitate a higher cadence, benefiting riders seeking a more aggressive riding position or those with specific biomechanical needs.
