Shimano Dura-Ace FC-R9100 Crankset

With the FC-R9010 cranksets, Shimano offers an extremely versatile crankset in the 11-speed Dura-Ace series, which can be combined with 6 different chainring sizes. To this end, the new 4-arm bolt pattern has been developed, which secures the chainrings precisely at the points subject to the greatest stress.

Hollow-forged chainrings, thin-walled hollow-forged crank arms and a reduced outer surface area bring the weight of the new Shimano Dura Ace FCR 9100 crankset down to 609 grams. The design of the 2x11-speed Hollowtech II crankset not only boasts a look and aesthetic with cult potential, but also ensures enhanced performance. A wider, yet lighter than its predecessor, crank arm and the large chainrings with Hollowglide technology increase stiffness and optimise power transfer to the pedal. Overall, the crankset is remarkably light – weighing in at 609 g for the compact version (50-34T) and 621 g for the standard crankset (53-39T)

The Shimano Dura Ace FC-R9100 crankset can be fitted with the following chainring combinations:

• 50-34 teeth
• 52-36 teeth
• 53-39 teeth
• 54-42 teeth
