Lightweight performance chainrings for 1x12 (and 1x11 - 1x10 1x9 setups too).

Phased machined teeth keep the chain well aligned.

Specifically angled teeth help the engagement with chain on 1 and 11 cog position.

Cut some extra weight with the 4 integrated threaded sockets, assembling requires only 4 male chainring bolts.
