Shimano FC-R9200 172.5 34T-50T Crankset

DURA-ACE FC-R9200 crank, the heart of the bicycle, ensures that no portion of your pedal stroke is wasted. With hollow arms and chainrings, weight is kept to a minimum but stiffness and shifting precision is maximized.The DURA-ACE FC-R9200 crank performs two vital functions: transferring your pedaling effort into the drivetrain and ensuring the fastest, most precise front shifting available. With HOLLOWTECH II crank arms to ensure light weight and Shimano's class-leading chainring designs, the FC-R9200 won't let you down.FeaturesOptimal balance of stiffness, strength, weight and rotational performanceHOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shiftingTECHNOLOGIESHOLLOWGLIDEHollow technology on outer chainringHigh rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.HOLLOWTECH Crank ArmHollow forged crank armsA lightweight crankset not only reduces the bike’s weight, but decreases rotating mass to aid in acceleration.The challenge is to reduce the weight of the crank without reducing its strength and rigidity.SHIMANO’s advanced forging technology has solved the problem through the HOLLOWTECH crank.Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight.HOLLOWTECH IIProviding the best balance of stiffness, strength, weight and rotating performanceThe 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. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. 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.The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design.High Precision SealingMoreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.24 mm Diameter Axle And BearingsWhy choose the 24 mm axle and bearings for the HOLLOWTECH II crankset?The diameter of the Bottom Bracket axle and bearings was of primary importance for the development because the Bottom Bracket axle area is tied to such key elements as stiffness, strength, weight and rotating performance.What’s important is the total balance of cranksetIn addition, taking the crankset as a whole, the total balance of crankarm rigidity, axle stiffness, bearing position and others is essential.Indeed, the crankset is designed by careful consideration of the total balance of those elements to prevent breakage.Outboard BearingFor most frames with 68 mm Bottom Bracket shells, HOLLOWTECH II with 24 mm axle can set the bearing position outside of the frame to provide better weight distribution and more stability.
