How to mount our oval chainring to SRAM GXP and BB30 crank:
You need to unscrew the 3 torx T25 bolts from the crank. Then remove the spider+chainring combo you currently have there. Clean the splines and put some grease on them. Position the chainring in place (note there is only one way to fit this chainring to Sram crank, so you don't have to worry how to do it). Close all 3 bolts to about 5-7Nm.
Check below which Sram compatible oval narrow wide chainring you will require for your Sram crank type. All Sram Cranks have exactly same mounting interface regardless the model or axle type. The only thing you need to determine is chainring offset.
