Shimano Ultegra FC-R8100 12 Speed Crankset

Season:2026

Brand:Shimano

Code:IFCR8100DX04

The Shimano Ultegra FC-R8100 12 Speed Crankset is built with stiffness, weight, and power transfer in mind.

Weighing around 700g, it has an extremely low rotational weight. The Ultegra FC-R8100 uses HOLLOWGLIDE for smooth shifting and excellent chain retention along with HOLLOWTECH II technology that stiffens the rotating mechanism, making power transfer more effective.

An integral part of Shimano's new 12-speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-speed shifting, the Ultegra crank brings performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements.

Features:

  • Optimal balance of stiffness, strength, weight, and rotational performance
  • HOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quick, precise front shifting
  • HOLLOWTECH II technology provides the best balance of stiffness, strength, weight and rotating performance
