How to mount Sram
You need to unscrew these 3 torx t-25 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 Sram chainring so you don't have to worry how to do it. Note that there are recesses for the bolts on one side). Close all 3 bolts to about 5-7Nm.
