eeWings Mountain and eeWings All Road use the SRAM 3-bolt Direct Mount interface. When choosing a chain ring for your eeWings crank, ensure that the chain ring is the SRAM 3-bolt Direct Mount. This interface is used by many chainring manufacturers so you have plenty of options to choose from.

We also have chainring spiders using the 3-Bolt Direct Mount interface, to allow for 5-bolt, 110BCD chainrings. The chainring spiders are available for both single (1x) and double (2x) chainring drivetrains. The 2x Spider allows for 32 tooth small chain rings, or larger chainrings. https://canecreek.com/product/crank-spider/
