Shimano Dura-Ace FC-R9200 Kurbelgarnitur

Lightweight and extremely stiff road bike crankset from the new DURA-ACE collection

The DURA-ACE FC-R9200 crankset, as the heart of the bicycle, ensures that not the slightest bit of pedaling power is lost. The hollow-arm cranks and hollow chainrings reduce weight as much as possible while optimizing stiffness and shifting precision.

The DURA-ACE FC-R9200 crankset offers two essential functions: converting pedal power into drivetrain energy and ensuring extremely fast and precise front shifting. Featuring lightweight HOLLOWTECH II crank arms and superior Shimano chainrings, the FC-R9200 crankset guarantees reliable function and performance. The FC-R9200 is also available with shorter crank arms to provide a suitable option for every type of rider.

Highlights

• Perfect balance between stiffness, stability, weight and rotational efficiency
• The HOLLOWGLIDE structure is lighter yet offers optimized power transmission and faster, more precise front shifting.
• New 54-40Z variant for high powertrain efficiency

Technologies used

In this chapter, we explain the technologies that the manufacturer uses in this product.

HOLLOWGLIDE – large hollow chainring
The extremely rigid hollow structure reduces weight while maintaining the same strength. This results in better power transmission and faster, more precise shifting at the front.

HOLLOWTECH – hollow-forged cranks
Lightweight cranks reduce the overall weight of the bicycle and, most importantly, the rotating mass crucial for acceleration. The challenge lies in reducing the weight of the crank without compromising stability and load-bearing capacity.
Shimano's state-of-the-art forging technology offers an ideal solution with the HOLLOWTECH crank. Just like a high-quality frame tube, the hollow-arm crank is extremely stable and durable despite its very low weight.

HOLLOWTECH II
Perfect balance between stiffness, stability, weight, and rotational efficiency. The HOLLOWTECH II technology concept was designed to create an optimized crankset that minimizes the rider's effort required for propulsion. The crankset's high stiffness ensures efficient power transfer while pedaling, while its low weight reduces rider fatigue, especially on longer rides. The crankset was developed with an optimal ratio of stiffness to low weight in mind. HOLLOWTECH technology enables extremely lightweight, hollow crank arms, manufactured using SHIMANO's exclusive forging technology to achieve maximum stiffness. Additionally, on the HOLLOWTECH II crankset, the right crank arm is rigidly connected to the bottom bracket axle, achieving an optimal balance between maximum stiffness and minimum weight. The external bottom bracket provides better weight distribution and increased stability, resulting in more efficient power transfer.
In the development of the HOLLOWTECH II crankset, emphasis was placed on an optimal balance between stiffness and rotational efficiency, as well as low weight and attractive appearance.
High-quality precision seals. The HOLLOWTECH II crankset also features high-quality precision seals in the bearing area to extend durability and maintain excellent rotational efficiency in the long term.

Scope of delivery
