\n\t\t\tShimano Dura Ace FC-R9200 2x12 Speed Chainset
\n\t\t
Features and Benefits:\n\t\t
\n\t\t\t- \n\t\t\t\tThe 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
\n\t\t\t- \n\t\t\t\tHollow outer chainring, giving vast improvements in rigidity and increased weight savings
\n\t\t\t- \n\t\t\t\tThe hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load
\n\t\t\t- \n\t\t\t\tThese industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength
\n\t\t\t- \n\t\t\t\tThe teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer
\n\t\t\t- \n\t\t\t\tThere is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines
\n\t\t
\n\t\tDura-Ace FC-R9200 crank, 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.
\n\t\t
\n\t\tThe 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.
