I have acquired (most of) a bike with a press fit Bottom Bracket BB92(?)
From the limited information I can find, it's for Shimano Hollowtech II

I'm trying to find Cranks for it with 160mm crank arms.
160mm crank arms seem to be sold separately from the hollow spline(?) (not sure of the terminology)
But I do NOT see the spline sold separately. All cranks seem to be permanently attached to the chain ring with the non drive side detachable.

Can anyone point me in the proper direction?

(I'm also open to other BB and crank solutions, but this is a free bike and would like to keep this on the inexpensive side)
