Shimano Dura-Ace R9200 Chainset – 12 Speed
The Shimano Dura Ace FC-R9200 Chainset, 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 chainset performs two vital functions: transferring your pedaling effort into the drivetrain and ensuring the fastest, most precise front shifting available. With Hollotech 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
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
HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
