This Shimano Dura-Ace chainring is a spare part for the FC-9000 11-speed crank. It has four arms arranged asymmetrically and a bolt circle diameter of 110 mm. Thanks to the many available numbers of teeth, a wide variety of 2x combinations can be created. The large chainrings (50 to 55 t) have a hollow profile to save weight (Hollowglide).

Note to Type Designation:

The type designation (one or two characters) helps identify the compatibility of various chainrings with other chainrings. Because the larger chainrings have specially-formed teeth and upward shifting assistance, only particular smaller chainrings will match to ensure proper shifting performance. An XY chainring should only be combined with another XY chainring. This applies to all other types as well.
