The DURA-ACE FC-R9200 crankset is the core of the bicycle, ensuring no pedal stroke is wasted and every watt is efficiently transferred to the drivetrain, while delivering the fastest and most precise front shifting performance. Featuring HOLLOWTECH II hollow crank arms and HOLLOWGLIDE hollow outer chainring, it minimizes weight while achieving maximum stiffness and shifting precision. Multiple crank arm lengths are available to suit riders of all sizes.
Key Features
HOLLOWTECH II Hollow Crank Arms
Hollow-formed crank arms reduce weight while maintaining extremely high rigidity, ensuring efficient power transfer and the optimal balance of stiffness, strength, weight, and rotational performance.
HOLLOWGLIDE Hollow Outer Chainring
The hollow-constructed outer chainring is lightweight yet maintains high strength, delivering better power transfer and faster, more precise front shifting.
New 54-40T Option
The new 54-40T combination enables a more efficient drivetrain, ideal for racing-focused riders.
