TheShimano Ultegra 52T Chainring for FC-R8000 11-Speed is designed for 11x2-speed drivetrains with 52 teeth (52-36) for FC-R8000 series cranksets
The Ultegra FC-R8000 chainrings, with their special tooth profiles, mounting bolts, and climbing aids, enable an exceptionally smooth and fast shifting process. This means that shifting under load—something previously only possible with the rear derailleur—is now achievable without any issues. Their carbon-fiber-reinforced plastic construction and aluminum teeth help keep weight low while increasing torsional stiffness. The hollow profile of the large chainrings also contributes to this.
