A 3x10-speed road crankset built on Shimano's two-piece Hollowtech II construction with an asymmetric 110/74mm BCD, sized for 50/39/30T chainrings. A 4-arm spider design balances stiffness and weight for everyday road and city riding.
Aluminum crank arms pair with a steel axle, and the chainrings combine aluminum, composite, and steel depending on the ring, at a 158.8mm Q-factor.
