Description
SHIMANO Dura Ace chainring FC-R9200 crank | LK110 asymmetrical inside
With their special tooth profiles, mount pins and climbing aids, the Dura Ace FC-R9200 chainrings enable a particularly smooth and fast shifting process. With them, shifting under load, as one would otherwise only be used to with a rear derailleur, is possible without any problems. Its carbon fiber reinforced plastic construction (large chainring) with aluminum teeth helps to keep the weight down while increasing torsional rigidity. The hollow profile of the large chainrings also contributes to this.
NOTE: The letter combinations (NK, NH, NJ) after the number of teeth should match for large and small chainrings. The Dura Ace FC-R9200 chainrings have been specially matched to one another thanks to their climbing aids and can only achieve their superior shifting performance in the combinations provided by Shimano.
