Converting Pedal Power into Propulsion at its Best
The Crank is the heart of the bicycle and ensures that no portion of your pedal stroke is wasted. With hollow arms and chainrings, weight is kept to a minimum but stiffness and shifting precision is maximized. The Shimano Dura-Ace FC-R9200 crank performs two vital functions, firstly transferring your pedalling effort into the drivetrain and ensuring the fastest, most precise front shifting available. With Hollowtech II crank arms to ensure lightness of weight and Shimano's class-leading chainring designs, the FC-R9200 won't let you down.
