The Shimano Dura-Ace FC-9000 34D 50/34 11S chainring is an original spare part for FC-9000 11-speed cranksets. It has four arms, arranged asymmetrically, and a circle of 110 mm holes. Thanks to the large number of teeth available, the most diverse 2-speed combinations can be produced. The large chainrings (50 to 55T) have a hollow profile (Hollowglide) to save weight.
