Revised racing bike crank in many variations

The new FC-R8100 crank of the ULTEGRA range offers the same fast, precise shifting performance at the front and the same efficient power transfer that Shimano is known for. In addition, it is available in even more length variants than before. With a length between 160 and 175 mm, the ULTEGRA cranks are now also suitable for smaller drivers, triathletes and anyone interested in shorter crank arms.

As a central component in Shimano's new 12-speed racing bike line-up, the FC-R8100 crankset is characterized by the Shimano-typical shift quality and transmission efficiency. Revised for a seamless 12-speed shift function, the ULTEGRA crankset is available in lengths from 160 to 175 mm. This means more performance and improved customization options for smaller riders, triathletes and riders with special biomechanical requirements.

Highlights

  • Perfect balance between stiffness, stability, weight and rotational efficiency
  • HOLLOWGLIDE structure is lighter and still offers optimized power transmission and faster, more precise shifting in the front
  • Chainring combinations with 52-36 and 50-34 teeth - crank arm lengths from 160 to 175mm

Technologies used

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

HOLLOWGLIDE - large hollow chainring
The extremely stiff hollow structure reduces the weight while maintaining the same strength. Better power transmission and faster, more precise shifting in the front.

HOLLOWTECH - hollow forged cranks
Light cranks reduce the overall weight of the bike and, above all, the rotating mass that is crucial for acceleration. The challenge is to reduce the weight of the crank without compromising stability and resilience.
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 resilient with a very low weight.

HOLLOWTECH II
Perfect balance between stiffness, stability, weight and rotational efficiency. The concept of the HOLLOWTECH II technology was geared towards the production of an optimized crankset, which minimizes the effort of the driver for the drive. The high rigidity of the crankset ensures efficient power transmission when pedaling, while its low weight relieves the driver, especially on longer journeys. The crankset was developed with a view to achieving an optimal ratio between rigidity and low weight. The HOLLOWTECH technology enables extremely light, hollow crank arms, which are manufactured using SHIMANO's exclusive forging technology in order to obtain maximum rigidity. In addition, the right crank of the HOLLOWTECH II set is firmly connected to the axle of the bottom bracket, which achieves an optimal balance between maximum rigidity and minimum weight. The externally mounted inner bearing offers better weight distribution and more stability, which ensures more efficient power transmission.
During the development of the HOLLOWTECH II crankset, emphasis was placed on an optimal ratio between rigidity and rotation efficiency as well as low weight and an attractive appearance.
High quality precision seals. The HOLLOWTECH II crankset also has high-quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over the long term.
