My frame says it has a "BB92 integrated bottom bracket".
The crank I want says it's compatible with "BB91 press fit".
Are these the same thing? I think Shimano started the idea of press-in bearings that work out to be the same as external cups on a 73mm BB shell. What do they call it?
My guess is the crank company's (Lightning) website has a typo.
