Forgive me forum for I have sinned. It's been 6 years since my last post :|

Does anyone know off the top of their head whether there are any middle rings out there compatible with an LX Hollowtech II M582. I realise that I may need a time machine or something.

Any help would be gratefully received. Many thanks!!

    Most 4 arm 32T MTB ring......the standard hasn't changed for about 20 years or so, my LX square taper takes the same rings.

    Right you are, thanks for that. Just that some of the Deore middle rings (couldn't find LX) I looked at had these tabs on them close to the bolt holes and some didn't. Is it just a case of filing them down if they don't fit properly as the bike shop reviews seem to suggest...?

    Thanks again, much appreciated.

    Not sure what tabs you mean, all the rings are designed to be a snug fit on the spider to locate them, Truvativ (SRAM) are slightly different to Shimano and Suntour (which are the same) but can be filed to fit, AIUI all Shimano are the same (4 arm MTB).

    Well that simplifies it at least. Happy days!

    For what it's worth I'll post what i thought were the differing rings and a link to the said reviews when I get a mo tonight/tmrw. Thanks again.

    Righto, so you don't think I'm going mad... here's the Deore middle ring with the tab-like bits on them, that I'm guessing the reviewers were referring to when they said they needed to be fettled/filed down(the reviews are in the same link):

    And here's the other Deore middle ring:

    I think I was getting confused my chainset's so old I wasn't sure which one would be appropriate. But that said, I'll have a proper look at me bike this weekend. Never easy this business when you're not so techy-minded.

    Cheers and all the best.

    The bolt holes and the location diamter are the same distance apart, the tab effect is because one is a photo of a 32T ring and one a larger 36T ring so the teeth are further out from the bolts - was praying you hadn't made that error!

    Right then, that's settled that! Sir, you are a gentleman and a scholar. I was blind but now I can see. I'll get tooth counting.

    And finally I might be able to get some sleep. Was dreaming chain rings last night. Must. get. a. life...
