• The HollowTech II 12-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders.

• Hollow outer chainring, giving vast improvements in rigidity and increased weight savings

• The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load.

• These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength.

• The teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer.

• There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines.

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.
