Got Raceface cinch ring on Raceface cranks that needs replacing. Bike is boost rear but a little confused by some of the internet talking about boost cranks vs offset chainrings....
I can’t see any helpful markings on the chainring but haven’t taken it off yet cos I’m still riding the bike until I order a new one....

0 is straight

3mm is usually just machined to one side of a flat chainring.

6mm is visibly dished.

Raceface Direct Mount rings are mostly (possibly all?) for 51mm chainlines, falls between the 48mm (6mm offset) for non-boost frames and 52mm (3mm offset) for boost frames. If you're buying a Raceface ring, no need to worry!
