I have a 52t sram red chainring. Wondering if that would be compatible with 11sp setup?

10 and 11s rings are basically identical. The chains have the same inner width.

On some cranks only the spacing between the rings can vary.

You'd think the spacing is less but on shimano r9100 they increased the spacing compared to 9000. Go figure? :)

Lets say you're using a 9s crank with 11s chainrings then there could be a risk of the chain getting stuck between the rings as they would be further apart. With 10 and 11 the spacing difference is nearly nothing.

They did that to help accommodate chainline issues arising from the wider rear dropout spacing (from 130mm to 135mm) required due to discs.

Sweet.. good to know it’s compatible. Now just need a 11sp cassette and then once all arrives should start putting it together.

Is KMC chain the lightest still?
