Shimano Cassettes

[wakou]

Hi guys, how I identify which cassette I have fitted? Is there a part # stamped on them? Does this tell me the exact configuration, ie tooth count or do I manually count the teeth on each? Thanks !

My 105 has the number of teeth stamped on each cog. Not sure about part number but then I've never looked for it.

Usually the part number is stamped on the cassette lockring.
