I need a couple of chainrings - The website offers Shimano A or B type
What is the difference ??
I think it's referring to the 42T or so ring and there's different ones for the inner of a double, or the middle of a triple. Does the Shimano website have labeled diagrams of your chainset?
Read your old rings.
Separate names with a comma.
