Shimano Dura Ace di2 R9200 crankset

Crank length: 172.5mm
Chainring: 54/40t

The Shimano FC-R9200 crankset converts the power you transmit to your 2x12-speed Dura-Ace road bike groupset into propulsion with high efficiency. It weighs around 20 grams less than the Ultegra model and its Hollowtech II design meets all your requirements for stiffness and stability. You will also benefit from the precise and fast shifting processes that you are used to from Shimano drivetrains. The crank arms are hollow, as is the large chainring, which is made partly of carbon, which allows for significant weight savings. With the exception of the axle, all essential parts are made of lightweight metal. FC-R9200 has an asymmetrical 4-arm hole circle diameter of 110 mm. It creates a chainline of 44.5 mm and has a Q factor of 148 mm. The gradation option from 40 to 54 teeth is specially designed for competition.
