Shimano Ultegra FC-R8000 Road Bike Chainring Black

The Shimano Ultegra FC-R8000 is the essential road bike chainring, designed for Shimano Ultegra FC-R8000 series cranksets (2×11-speed drivetrains). It offers reliability and efficiency, whether in competition or during intense efforts on the road.

This chainring is ideal for benefiting from a wide range of gear ratios. Thanks to its Hollowglide technology with a hollow structure, it combines optimal rigidity with lightweight performance, ensuring precise and efficient power transfer with every pedal stroke.

Made of anodized aluminum reinforced with CFRP (Carbon Fiber Reinforced Polymer), this chainring is both strong and light. Its standard 4-arm asymmetric architecture with 110 mm BCD guarantees perfect compatibility with FC-R8000 cranks and simple, secure mounting.

Highlights

• Maximum power transfer: The Hollowglide structure and CFRP reinforcements prevent torsional deformation during sprints.
• Hyperglide shifting: Smooth and precise chain transitions for 11-speed drivetrains, even under heavy load and during sudden accelerations.
• Racing configuration: 53/39 tooth count ideal for fast courses and flat races.
• Shimano OEM reliability: Original part ensuring the longevity and precision of your R8000 groupset.
