Where can I find 7/8s chainrings that will fit M900 and LX BCD110?

Hi All

All in the title really, have a couple of cranksets which I would like to use again but chainrings are used. They are for 7s 1993 / 1994 bikes (were on eldrdige grade and team marin respectively). I see a lot of 9/10s that would go on BCD110 but I wish to still run 3x7s for now and am unsure those 9/10s will work fine.

Any insight much appreciated.
 
As a rule if they do 9 they should do 7 or 8. Sometimes 10s had an offset to the teeth from the tab, so thin chainring spacers might be necessary.
 
Stronglight rings work fine. Zicral or dural.

Thank you, they are referenced for 9/10s. Does that mean that those rings would work the same with a 7/8s chain, as well as a 9s and 10s chain out of the box?

Or am I going to need to fiddle with ring spacers of different thickness (I really hope not :LOL:)
 
No they work fine. I've used them for years.

The other ive used is TA zephyr, but those are well spendy now. They are also quoted as 10 speed.
 
The inside dimensions of 7,8,9 speed chain links are essentially the same so the chainring teeth are also the same dimensions.
