shimano m590 chainset. 9 speed only?

[chocjohn9]

Can I run 10 speed gears, sti, rear mech etc and still use this chainset?
I realise that Shimano say it is for 9 speed but there are plenty of chainsets out there that aren't gear number specific.
If not I'd be interested to know why not!
Thanks

Interesting question, but wouldn't it be better in the tech section?
You may well get faster answers.

I have an m590 48/36/26. I recently found some barely used t611 10 speed rings on ebay for £11 as future spares. Both 26t cogs are stamped 9/10 speed (58g), the middle rings are identical (96g), the m590 outer ring (not drilled for a guard) is 98g the t611 outer ring is 110g and I think the extra weight is reinforcement to fit a chainguard.

IIRC there are two different versions of FC-M590, and one is meant for 10s

Yes it should be in technical but that seems to be ignored so often.
Most chainsets work with most chains. 7/8 speed ones can allow 11 speed chains to drop in the gap if 11 speed mechs are used and 11 speeds don't play nicely with with wide 7 speed chains . All generalisations. Most are fine if the numbers are close. Wouldn't worry me if it was one out.

Thank you for the replies and images.
I will fiddle in the shed and report back. This boils down to being a bit tight and lazy. Not changing the chainset would be great.
I did mean to put this in the technical section, but only realised after I'd posted and didn't know how to move it.

For reference - the answer to my own question is yes.
I am jow running a ten speed set up -sti, chain, front and rear derailleurs and cassette whilst keeping my 9 speed deore chainset.
Happy days. Much expense spared.

Thanks for reporting back choc.

The answer to your question is an unequivocal yes, it'll work perfectly with 10 speed.
