These are the narrow wide 1x chainrings that go with the White Industries MR30 cranks. (This includes the M30 AND the R30) Their center lock ring design makes swapping between sizes or even 1x to 2x a breeze. Their short tooth, tall tooth design combined with the narrow wide teeth will keep your chain in place through the washiest of the washboard roads. These rings are compatible with all chain sizes including 11 & 12 speeds.
Works with both M30 and R30 Cranks.
