Shimano FC-R9200 DURA-ACE 12Speed Front Chainwheel

DURA-ACE FC-R9200 crank, the heart of the bicycle, 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 DURA-ACE FC-R9200 crank performs two vital functions: transferring your pedaling effort into the drivetrain and ensuring the fastest, most precise front shifting available. With HOLLOWTECH II crank arms to ensure light weight and Shimano’s class-leading chainring designs, the FC-R9200 won’t let you down. The FC-R9200 is offered in even shorter crank arms lengths to offer fit options for any rider.

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
– New 54-40T option to realize the most efficient drivetrain
