Shimano Ultegra FC‑R8000 53T‑MW Road Bike Chainring Black 2025

The Shimano Ultegra FC‑R8000 53T is the essential road bike chainring, designed for Shimano Ultegra FC‑R8000 cranksets (2×11-speed drivetrains). It delivers reliability and performance, whether in competition or during intense road efforts.

This 53-tooth chainring pairs with a 39-tooth inner ring (Type MW) to form a 53/39 road bike setup, providing a wide range of gearing. Thanks to its Hollowglide technology with hollow construction, it combines optimal stiffness with light weight, ensuring precise and efficient power transfer with every pedal stroke.

Made from anodized aluminium reinforced with CFRP (Carbon Fiber Reinforced Polymer), this chainring is both strong and lightweight. Its standard 4-arm asymmetric design with BCD 110 mm ensures perfect compatibility with FC‑R8000 cranksets for a simple and secure installation.

Key features

• Maximum power transfer: Hollowglide structure and CFRP reinforcements prevent torsional flex during sprints.
• Hyperglide shifting: Smooth and precise chain transitions for 11-speed drivetrains, even under heavy load and during accelerations.
• Competition setup: 53/39 tooth gearing ideal for fast courses and flat races.
