Shimano Crank Bolt Patterns
 

I have two bikes with SRM Origin Powermeters. One is setup for 9000 Chainrings and the other for r8000. I would like to try some less expensive chainrings and am looking at Rotor products. My question, are all 4 bolt 110 paterns compatible with Shimano bolt patterns. My second question, if not, how do you tell the difference? Thanks.
