Shimano Ultegra FC-R8000 11-speed Chainring

The Shimano Ultegra 11-speed chainring for the FC-R8000 crankset

The Shimano Ultegra FC-R8000 11-speed chainring contributes together with the other drivetrain components to a smooth and fast shifting process. It is asymmetrical, has a bolt circle diameter of 110 mm and is made of aluminium or an aluminium-carbon composite. The large chainrings (except 46 t) are hollow (Hollowglide technology) to save weight.

Note to Type Designation:

The type designations (with one or two letters) indicate that the chainrings can be combined with each other. Since the large rings have specially shaped teeth and shifting aids that make it easier for the chain to climb, full shifting performance is only guaranteed with matching small rings - and vice versa. A chainring of type XY should therefore only be ridden with a chainring of type XY. The same applies to all other types.
