Crankset Shimano GRX FC-RX610-2 (2x12-speed)
Shimano GRX FC-RX610-2 2x12-speed crankset is designed for energetic group rides and aggressive gravel racing. It balances weight savings and optimised efficiency to deliver smooth and controlled pedalling on fast gravel sections and technical terrain alike.
The 46-30T chainring combination is gravel-optimised, maintaining tighter gear steps to help riders control cadence and hold position in the group. Smaller increments allow precise rhythm management on mixed terrain, while the wide gear range supports both high-speed sections and steep climbs.
The 2-piece HOLLOWTECH construction ensures excellent stiffness and efficient power transfer. A 47 mm chainline and 151 mm Q-factor are tailored for wider tyres and gravel frame geometry. Available in 165, 170, 172.5 and 175 mm crank lengths for an optimal rider fit.
