Chainline - does 3 mm make a difference?

[D(C)]

I have a Boost frame, and recommended chainline is 52 mm. I accidentally picked up a zero-offset chainring, which gives a 55 mm chainline. Am I in for trouble or should I just run the chainring?

If you spend any amount of time in the larger cogs, your chainline is going to be pretty bad.

I just spent a couple hours building a custom set of spacers and bolts to move my 1x ring inboard 1/8" or 3.175mm, which should help with chain noise.

If it was 3mm inward you'd get chain rub on the small cogs which is annoying but livable.

However, in your case, I would get the right ring because that is a lot of angle to run on a short chain length when in the large cogs. It'll shift shittier and the chain will jump down a cog or two with the mere thought of backpedaling when in said larger cogs. It will also cause far more wear on the chainring and large cogs.

Cool. Yeah I'm thinking I will get a regular 6 mm offset ring, which I'm reading actually gives a better chainline with Boost than a 3 mm offset Boost ring. If that's the case, the zero-offset ring would put me a full 6 mm outboard from ideal.
