Description
SHIMANO chainring Dura Ace FC-R9100 crank LK 110 outside
With their special tooth profiles, mount donate and climbing aids allow Dura Ace FC-R9100 chainrings a particularly soft and fast switching. So with them a shift under load, as it was usual only from the rear derailleur, easily possible. Its construction of carbon fiber reinforced plastic with aluminum teeth helps to keep the weight low while increasing torsional rigidity. The hollow section of the large chainrings also contributes to this.
NOTE: The letter combinations (MS, MT, MW, MX) behind the numbers of teeth should match for large and small chainrings. The Dura Ace FC-R9100 chainrings have been specially tuned by their climbing aids and can only achieve their superior shifting performance in the combinations provided by Shimano.
