possibly and probably
but note even the difference in the 2 x11 chainrings / mounting
2x11 600 crank (top pic) - 2x11 810 crank (bottom pic)
can’t recall if the chainring fasteners are the same - had that info at one point but was unable to locate
Well, I didn't find any spacing differences and didn't even have to tweak the FD. The recent incident occurred because I tried to fix something that wasn't broken!
The 46/30 rings (from a 600 crankset) will mount correctly on the 810 cranks. The only issue I had was that the chain catcher pin had to be shortened. Shimano put 2 scribe (cut) marks on the pin so these same rings must be used elsewhere.
