SHIMANO Ultegra chainring FC-R8000 crank | LK110 asymmetric inner
With their special tooth profiles, mounting pins and climbing aids, the Ultegra FC-R8000 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) after the number of teeth should match for large and small chainrings. The Ultegra FC-R8000 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.
