This Shimano Dura Ace chainring is an original spare part for the FC-9000 11-speed crank. It has four asymmetrically arranged arms and a 110 mm bolt circle diameter. Thanks to the available tooth counts, the most diverse 2x combinations can be produced. The large chainrings (50 to 55 Z) have a hollow profile to save weight (Hollowglide).
