Looks good.
I had trouble with mounting Dura Ace rings on the ALDHU spider. The stack of spider thickness and inside of the chain ring bolt hole thickness was too small and the chain ring bolt wouldn't snug sufficiently to keep the ring on tight. Apparently some chain rings are thicker than others as a friend said FSA rings work well. I solved the problem by getting the Power2Max powermeter spider. But that necessitated getting the ALDHU road axle and BB. It's the rainy season in the PNW so I haven't been able to track test it yet.
If anyone needs the Rotor ALDHU track spider, track axle, and track BB, I have a spare set.
