The Shimano Dura-Ace FC-R9200 Hollowtech 2 Crankset ensures maximal power transfer from the pedals to the chain.

The FC-R9200 Crankset is offered in a variety of crank arm lengths to suit any rider. The new 54/40T chainring option provides a gearing choice for riders who need the speed – such as time trialists and power descenders.
