You can also install Shimano 12-speed chainrings on this power meter such as DURA-ACE 9200 chainrings, Ultegra R8100 chainrings or 105 R7100 rings. However, the shape of the chainrings does not match the power meter (please see the image below). This is a cosmetic issue only, but we understand this is important to customers.
Please note, the DFour is not compatible with DURA-ACE 9000, Ultegra 6800 or 105 5800 chainrings. If you have any of these older chainrings, you would need to upgrade your chainrings to one of the compatible versions above.
