Shimano GRX-610 12-Speed Crankset

Looking for a Shimano GRX-610 12-speed crankset for your gravel bike? This crankset has 172.5 mm cranks, a single 40- or 38-tooth chainring or a 30-46-tooth double, and a Hollowtech II interface, with 9/16-inch pedal threads. It is designed for riders tackling gravel tracks and mixed surfaces who use a 12-speed system with a HG chain.

Choose according to the chainring tooth count. The 40t and 38t are single-chainring versions: the 38t has a smaller chainring and therefore slightly lower gearing. The 30-46t has two chainrings, with 30 and 46 teeth. The bottom bracket is not included and must be purchased separately, so check it before ordering.

Founded in 1921 in Sakai, Japan, by Shozaburo Shimano, Shimano is still based in the same city today. For cyclists, it makes drivetrains, brakes, wheels, pedals and cycling shoes. Its history in bicycle components began with the production of freewheels in 1922.
