Shimano chainring Ultegra FC-6800 crank LK110 outside
With their special tooth profiles, mount donate and climbing aids allow Ultegra FC-6800 chainrings a particularly soft and fast switching. This enables them to easily switch under load, as was otherwise only the case with the rear derailleur. Their construction made of glass fiber reinforced plastic with aluminum teeth helps to keep the weight low while increasing the torsional rigidity. The hollow profile of the large chainrings also contributes to this.
NOTE: The letter combinations (MB, MA, MB, MD) behind the number of teeth should match for large and small chainrings. The Ultegra FC-6800 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.
