Shimano Dura-Ace FC-R9200 Crankset (Black) (2 x 12 Speed) (Hollowtech II) (165mm) (50/34T)

The Shimano Dura-Ace FC-R9200 Hollowtech 2 Crankset ensures maximal power transfer from the pedals to the chain. Hollowtech II technology keeps the weight of the cranks down and the top-of-class chainring design provides the fast and precise shifting of Shimano's 12-speed Di2 groupset. 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.

Features:

• Optimal balance of stiffness, strength, weight and rotational performance
• Hollowglide structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting
