SHIMANO chainring Dura Ace FC-R9100 crank LK 110 Outer
With their special tooth profiles, locating pins and climbing aids, the Dura Ace FC-R9100 chainrings enable a particularly smooth and fast shifting process. This makes it possible to shift gears under load without any problems, as was otherwise only possible with the rear derailleur. Their construction from carbon fiber-reinforced plastic with aluminium teeth helps to keep the weight low while increasing torsional rigidity. The hollow profile of the large chainrings also contributes to this.
NOTE: The letter combinations (MS, MT, MW, MX) after the number of teeth should match for the large and small chainrings. The Dura Ace FC-R9100 chainrings have been specially matched to each other with their climbing aids and can only achieve their superior shifting performance in the combinations specified by Shimano.
