The Shimano GRX FC-RX610-2 crankset pairs a 46-30T double chainring with Shimano's 12-speed GRX gravel groupset, giving riders a wide range for mixed-terrain riding and racing. This 172.5mm arm length suits riders seeking a direct, stiff pedalling platform, while Shimano also offers 165mm, 170mm, and 175mm options to match crank length to fit and riding style.
Built on Shimano's Hollowtech II spindle interface, the crankset uses a 110mm Shimano Asymmetric outer chainring bolt circle with an 80mm inner BCD, and accepts standard 9/16 inch pedals. It suits 135/142mm Road Disc hubs on frames with chainstays longer than 415mm; a compatible bottom bracket is sold separately.
