I have a cheapish (okay - cheap) Shimano FH-M525-A MTB rear hub (QR, 10-speed). The freehub body has a fair bit of play so I want to replace it. There are any number of supposedly-identical replacements available on e.g. Amazon, etc., but I was thinking if there is a compatible one with more engagement points than the pretty-awful 16 I currently have, I might as well get that while at it. Something similar to a Deore -> XT upgrade for this part.
I see most Shimano MTB hubs now have either 32 or 36 EP's, which while not high-end would be a significant improvement on my 16. The freehub body I have is the
Y3SP98110 (shown here as part of the hub). After much searching I've been unable to find any data to support confidently selecting a better alternative. It seems at this granularity of part (rather than e.g. the whole hub) there is not a lot of information going, especially on Shimano's site (as already noted here).
Does anyone know a part number for a compatible-but-better freehub body that I can search for?
