Find the Shimano chainring you need at Escapa. The Shimano Ultegra FC-R8100 Chainring, with its special tooth profiles, mounting pins, and climbing aids, allows for particularly smooth and fast shifting. With them, shifting under load—which you’d otherwise only be used to with a rear derailleur—is possible without any issues. Their carbon-fiber-reinforced plastic construction with aluminum teeth helps keep weight low while increasing torsional stiffness. The Hollowglide profile of the large chainrings also contributes to this.
NOTE: The letter combinations (NK, NH) following the tooth count must match for both large and small chainrings. The Ultegra FC-R8100 chainrings have been specially matched to each other thanks to their climbing aids and can only achieve their superior shifting performance in the combinations provided by Shimano.
