Dura Ace 2×11-speed Crank FC-R9100 53/39
The FC-R9100 HOLLOWTECH II crank shaping improves upon DURA-ACE?s iconic 4-arm design, adding strength and rigidity while minimizing weight.
Most advanced component group of all time: The Shimano Dura Ace 2×11-speed Crank FC-R9100 Shimano?s Rider Tuned gearing offers a number of chainring configurations with a singular BCD for ease of use and versatility. Through redesigned chainring tooth profiling, the DURA-ACE R9100 crankset is adapted for the latest disc brake frame designs without the need to increase q-factor. Enhanced design saves 7g while maintaining rigidity and iconic 4-arm construction Optimized crank arm design strengthens key stress zones.
With the introduction of DURA-ACE R9100, Shimano has reestablished the new benchmark for road performance by improving each component and incorporating its newest digital technologies. DURA-ACE R9100 delivers unparalleled performance, highly-refined ergonomics and immense customization to maximize every rider?s potential.

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. 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. Shimano DURA-ACE R9100 (Di2)
