Find your Shimano component replacement parts at Escapa. The Shimano Dura-Ace 34T-NK FC-R9200 Chainring, with its special tooth profiles, mounting pins, and climbing aids, ensures a particularly smooth and fast shifting process. With these chainrings, shifting under load—which is otherwise typically only possible with a rear derailleur—is no problem at all. Their carbon-fiber-reinforced plastic construction (large chainring) with aluminum teeth helps keep weight low while increasing torsional stiffness. The hollow profile of the large chainrings also contributes to this.
NOTE: The letter combinations (NK, NH, NJ) following the number of teeth must match for both the large and small chainrings. The Dura-Ace FC-R9200 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.
