I don't mind the bit of work TBH - I'll research that just to be certain I want to spend the time....and you're totally right Seamuis, it's the 144bcd that's the culprit. I did however find a bunch of old race dura-ace chainrings on ebay and NJS export. Most of them coming from Japan and used, but seem to be in ok condition. They're also half the price of a new 1/8 chainring which is kinda appealing. I don't feel the need to change the entire drivetrain so I'll stick with the Andel and work around it. It fits the bike anyhow.

Thanks again for all the suggestions, I really appreciate the help.
