Shimano chainring Dura Ace FC-9000 crank LK110 inner
With their special tooth profiles, locating pins and climbing aids, the Dura Ace 9000 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 and at the same time increase torsional rigidity. The hollow profile of the large chainrings also contributes to this.
Note: The letter combinations (MA, MB, MC, MD) after the number of teeth should match for large and small chainrings. The Dura Ace 9000 chainrings have been specially matched to each other by their climbing aids and can only achieve their superior shifting performance in the combinations provided by Shimano.
