Thanks for the input.

So when I converted from 32T round to 32T oval I bot an absoluteBlack chainring. It was ~100$ shipped. I'm trying to save some money this time around, especially since I'm not sure if I should go 28T or 30T. I found a company on Amazon that sells HG+ 12 speed "compatible" single chainrings. The one caveat is you cannot use a shimano 12-speed quick link with their chainring. The shimano 12-speed quicklink is too narrow. I measured my quicklink widths : 3.45mm. The width of the links on the chain is ~3.72mm.

"If you are non-shimano brand 12 speed chain, it works for your 12s system. If your chain is shimano brand original 12 speed chain, you have to buy a Non-shimano brand 12s quick link to replace the original shimano 12s quick link."

Here's the company's product list on Amazon. Anyone have any experience? Seems like they get good reviews.
