Product Description
The Shimano Dura-Ace Crankset, FC-R9200 12-Speed 172.5mm 50-34t is a high-end, premium crankset designed for road cycling. It is part of the Dura-Ace R9200 groupset, which is Shimano's top-of-the-line groupset for road bikes.
The crankset features 50-34t chainrings, which provide a wide range of gearing options for both climbing and high-speed riding. The 172.5mm crank arm length is a common size for road bikes and provides a good balance between power transfer and comfort.
The FC-R9200 crankset is designed to work with Shimano's 12-speed road bike groupsets, which include the Dura-Ace R9200 and Ultegra R8100 groupsets. It uses Shimano's Hollowtech II technology, which provides a lightweight, stiff and strong design.
The 50-34t chainring option provides a wide range of gearing options for both climbing and high-speed riding, while the 52-36t option offers a wider gear range for high-speed riding, while still allowing for efficient power transfer during climbing.
