Is there a shortage of the smaller bcd chain rings

As far as I know mine is a 110bcd the other being 130bcd iirc

All I bloody want is a rider condition alloy 43/44t to finish this, and all anyone's got is the larger 130bcd rings.

Attached a pic of my tiny spider that needs a small ring, oo er

Wasnt alot of chain rings both?
I might still have a blue Suntour ring that I painted black somewhere. Think its got 42t.
Are you after any particular colour?

Not bothered it will be stripped and buffed unless it's blue or red
Cheers man

Found the Suntour its a 41t, Also found some others one of which is 44t and another that is 45t will check the BCD for you.

The 44t one is 110 BCD, I have two, One old school one and a new school one. Here's some pics.

No idea on make, Looks like someone has had a go at removing anno already. I reckon a caustic soda bath and a polish will be fine. You can see black inside the holes and by the teeth.
This NS one I think came on a 2004 GT race bike I bought new.

Hardly used before I swapped it out.
If you want either of them LMK. Price wise say £4 each posted.

That BCD gauge you have Gary is a handy piece if kit

Think it came with a FSA sprocket I bought.
Would it be possible to scan it and upload it so people can print it off. Only problem is making sure it stays the correct size. I'm in no way a computer genius
