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.
