Just to clarify, Dura Ace rings work fine with the Power2Max powermeter spider that you can get with a Rotor 3D+ or 3D24 crankset. It looks like Joe Lo is running a Campy ring on his Power2Max. It's the Rotor ALDHU track spider that needs fiddling. I've never used a Rotor 3D+ or 3D24 track spider, so have no comment on their compatibility.
