I'm looking to order the tool to remove the cassette lockring on my bike, but I'm not sure which tool to get. Is there a way to tell just by looking at it, or do I have to look it up using the make and model of the cassette?
While I was looking for a more generic answer, specifically I have a Shimano CS-HG20-9 Cassette. Seems to be a freehub style, and probably takes FR-5 tool. However, I wanted to know if there was a way to know for sure that the tool will fit, so I don't waste time ordering the wrong tool.
