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. Thanks to HOLLOWTECH II and HOLLOWGLIDE technologies, Shimano's class-leading chainring designs, the FC-R9200 strikes the optimal balance of stiffness, strength, weight and rotational performance.
