Attach this chainring to your ZIS-MTB crankarm for use with 1x11 components. This model has 0mm offset which creates more clearance between the chainstay and the chainring.
These rings fit SRAM GXP-spindled cranks and Zinn ZIS pro MTB cranks. If you're looking for a ring that helps on punchy singletrack and hills, give one of these elliptical chainrings a try. Its proprietary design has an ovality of 10% and a timing of 112 degrees after top dead center which provide the beneifits of an oval ring without the traditional downsides of oval rings.
