i don't know if the 2015 update even applies to cranks, or if its just shifters/derailleurs.
obviously, i'm inquiring about 11-speed.
What is the difference between pre-2015 Chorus vs Record cranks?

Pretty sure the <2015 Chorus crank arms weren't hollow - they had some kind of foam core.
R/SR were hollow, plus the usual addition of different bearings / Ti spindle.
2015+ I'm 99% sure there is no difference whatsoever in the crank arms between C/R/SR.

There is like a 30 gram difference between the two.
