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.
