Looking through wolftooth website, it seems that this version "GR8" is marketed for grx crank. Rather annoying that they list this item in the normal 110 bcd listing as well. "SH" version might work, but do your own test.
For future reference. GR8 version of this chainring doesn't seem to be compatible with pes base. I ended up having to buy a normal crankset to finish my build.
Hopefully i can repurpose this powermeter to my ultegra roadbike.
