Are 7800 and 7900 Durace bottom brackets interchangeable?

As the per the title ...

Thanks

Yes

And again yes. In fact all Hollowtech 11 seem to be, and I've used a 7900 bb with Sora and Ultegra cranks.

I've got a 7900 BB on my hybrid with Deore chainset no problem. It seems that hollowtech II really is a standard and all hollowtech II things work together as you'd hope

Of course the next question is what I should replace the square taper BB and chainset on the Trek with when they wear out / I feel rich...
