Shimano's nomenclature is mostly pretty logical once you look into it. The first two letters before the hyphen indicate the individual component (except SM - Small Parts - where the next part of the code suggests where they relate to). After the hyphen the first letter indicates the purpose; R=Road, M=Mountain, T=Trekking/Touring, A=All-purpose, RM=Road/Mountain (parallel to A-series). The first number indicates the spec level, higher number = better. Non-series parts will typically correlate to main groupset gradings. The second digit in three- or four-digit codes is the series evolution, sometimes matching the main groups, sometimes not. The final digit (or two in the case of four-digit codes) identifies particular variations in a model range.

I didn't bother replying earlier as it felt a bit pointless saying "If it's a Shimano hub it will have the word 'Shimano' written on the hub shell and the model code written under it, so assuming you can't see that then it's probably not a Shimano hub".

I'm preempting his next question will be about servicing the bearings. I'm assuming there's a video out there that explains the process

There's an eBay seller based in Japan (not sure where) called Hobby_Japan whom I have used a few times for Shimano workshop tools and occasionally parts. OK pricing but they do carry small parts. I would agree with you that the cup/cones are probably just needing a good clean and maybe new loose balls but also understand why he would probably want a new kit for simplicity's sake.mikesbytes wrote:He's looking at buying a new assembly. Gut feeling tells me he just has to disassemble, clean, grease and reassemble but its his decision and he's the one who's actually looked at.
