The HollowTech II 12-speed Dura-Ace chainset strikes the perfect balance between light weight and rigidity, making it the top choice for elite road racers worldwide.
The Dura-Ace FC-R9200 crank, the heart of the bicycle, ensures every pedal stroke is efficiently transferred to the drivetrain. Featuring hollow arms and chainrings, it minimizes weight while maximizing stiffness and shifting precision.
The FC-R9200 crank excels in two critical areas: converting pedal effort into drivetrain power and delivering the fastest, most precise front shifting. With HollowTech II crank arms for reduced weight and Shimano's industry-leading chainring designs, the FC-R9200 is built to perform. Additionally, it is available in shorter crank arm lengths to provide a perfect fit for any rider.
HollowGlide
The outer chainring features hollow technology, offering high rigidity while reducing weight. This design ensures better power transfer and delivers quicker, more precise front shifting.
HollowTech Crank Arm
Hollow forged crank arms make this crankset lightweight, reducing both the bike’s overall weight and rotating mass for better acceleration. The challenge is to cut weight without losing strength and rigidity.
Shimano’s advanced forging technology achieves this with the HollowTech crank. Like high-quality frame tubing, a hollow crank arm offers exceptional strength and rigidity while remaining very lightweight.
HollowTech II
HollowTech II technology offers the optimal balance of stiffness, strength, weight, and rotational performance. Designed to maximize power transfer, this crankset ensures efficient pedaling through its rigidity. Its lightweight design also helps riders maintain endurance over longer distances, enhancing overall cycling performance.
Features:
- Hollow outer chainring, giving vast improvements in rigidity and increased weight savings
- Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
- HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
- There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines
- The teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer
- These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength
- The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load
