Helping a friend get a PM he’s running 10 Speed Dura Ace 9000 but the current available Stages or 4iiii are all 9100. Is the spline on these two Dura Ace cranks the same meaning apart from the cosmetic element the non drive side 9100 will just fit on the existing 9000 spline ?
Thnx.

Dura Ace 9000 is 11 speed but aside from that point, yes, the interface is the same.
