Crankset Shimano GRX FC-RX610-1 (1x12-speed)

Shimano GRX FC-RX610-1 1x12-speed crankset is designed to deliver optimal gravel gearing for a wide range of riding needs. It balances weight savings, stiffness and efficiency to meet the varied demands of mixed-terrain riding, from fast cruising to steep gravel climbs.

Paired with a 38T or 40T chainring and either a 10-45T or 10-51T cassette, riders can choose between tighter gear steps for smooth cadence or an ultra-wide range for challenging ascents. The 2-piece HOLLOWTECH construction ensures stiff and efficient power transfer while maintaining durability for long adventures.

A 49.7 mm chainline and 151 mm Q-factor are optimised for wider tyres and gravel frame geometry. Available in 165, 170, 172.5 and 175 mm crank lengths, the FC-RX610-1 provides additional fit customisation for individual riders.
