SHIMANO GRX CRANK FC-RX810-1 42T 172M 5 IFCRX8101DXB2

The new GRX FC-RX810 Hollowtech II crank from Shimano was developed for 1 x 11-speed to handle a wide variety of terrain and driving styles.

For gravel, road and cyclocross use: Shimano GRX 1x11-speed FC-RX810 Crank 42T

All versions feature a 2.5mm wider chain line that gives more space in the frame design and wider tyres. GRX 1-speed cranks minimize the complexity of shifting only at the rear of the cassette (optional RX800/600 40T cassettes or RX800 42T cassettes), and are equipped with chainrings with SHIMANO's DYNAMIC CHAIN ENGAGEMENT+ toothed treads that provide optimal chain retention especially on bumpy surfaces. The GRX RX810 2-speed crank, on the other hand, is characterised by the specific 17-tooth difference between the large 48T and small 31T chainrings, the widest gradation of all SHIMANO components to date. Together with the 46-30T cranks of the RX600 series (10-speed and 11-speed), the 2-speed cranks of the GRX family thus offer more than enough bandwidth for super steep climbs and high speeds in the flat or on descents.

SHIMANO's GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.
