The DURA-ACE FC-R9200 crankset, as the heart of the bicycle, is designed to transfer power as efficiently as possible. The Hollowtech II technology with an integrated disc spindle and hollow aluminum arms reduces weight, increases structural stiffness, and conveys the rider's generated power without unwanted losses. The discs are mounted through an asymmetrical four-arm spider with no visible external bolt, enhancing both appearance and aerodynamics. The precise and faster gear shifting available on the market will undoubtedly improve the cycling experience. These features are especially appreciated by road cyclists and triathletes, where quick mechanism operation is a critical factor.

• Technology: Hollowtech II - Perfect balance of stiffness, durability, low weight, and performance.
• The stiffness of the crankset, thanks to the integrated spindle, ensures pedaling efficiency, while its weight, which is a crucial element of the crankset, supports longer-distance cycling.
• Shimano aimed to achieve the optimal balance between stiffness and the lowest possible weight of the crankset.
• The use of their own forging technology on the ultra-lightweight hollow crankset ensures stiffness.
• The outer bearing system of the bottom arm provides better load distribution and improved stability during pedaling, offering more efficient power transfer—all in a lightweight and sleek design.
