Shimano DURA-ACE FC-R9200 2 x 12-speed HOLLOWTECH II crankset not only brings a cult-like look and aesthetics, but also ensures even better performance. THE SCIENCE OF SPEED: Shimano DURA-ACE 2x12-speed Crank FC-R9200. Shimano has been working for years to provide you with an advantage of seconds. 12-speed DURA-ACE R9200 is the fastest groupset ever and the pinnacle of SHIMANO technology and innovation. Speed was the key driver for the development of this generation road groupset. That's why every component has been revised, refined and optimised to make you even faster - whether to leave the peloton behind you or to win the final sprint on the Champs-Élysées. The DURA-ACE FC-R9200 crankset performs two crucial tasks: It converts pedal power into driving force and ensures extremely fast and precise front shifting. At the same time, dual-sided FC-R9200-P power meter processes all this data with outstanding accuracy. In addition, the lightweight HOLLOWTECH II crank arms and SHIMANO's leading chainring design further contribute to the FC-R9200's top ranking!

TECHNOLOGIES

HOLLOWGLIDE - Hollow technology on outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.

HOLLOWTECH II - Providing the best balance of stiffness, strength, weight and rotating performance. The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
