Ultra BB cups are the same geometry but the SR ones are missing the seal that the other series need. So, if you use a SR cup with a Chorus bearing, the bearings will get fouled sooner/ You should be able to mix and match newer Chorus/Record components but not with the Power shift stuff (Potenza, Centaur). Pictures show 2015+ chrous crankset and super record cup (no idea of the vintage of it)
