Answer: All current e*thirteen chainring designs (Helix, Guidering SL, Guidering UL, and E*spec) are compatible with all* 11s & 12s mountain bike chains on the market.
*Exceptions:
SRAM® FlatTop™️ chain, including T-Type - See this article.
Campagnolo® Ekar™️ 13-speed chains. Campy's 13 speed chains are too narrow to fit on any current e*thirteen chainrings.
