Vändad Shimano GRX FC-RX810-1 172.5mm 1x11-speed 40T

GRX FC-RX810 Hollowtech II crank from Shimano was developed for 1x11-speed to handle a wide variety of terrain and driving styles. For gravel, road and cyclocross use: Shimano GRX 1x11-speed FC-RX810 Crank 40T. All versions feature a 2.5 mm 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.
