Good morning all
I have a frame that measures 89mm in the bottom bracket area so apparently I need a bb92/PF92 BUT it's threaded
What are my options if any ??
Thanks
A quick look online suggests a T47 bottom bracket, what diameter is the crank spindle? A T47 appears to be for a 30mm crank.

I was hoping to use a Shimano crank
What frame is it?
It's a Corsair Krakenwagen
Have a look here wheelsmfg.com/bb-standards and hopefully that will help you find what you're looking for.

Hope PF41 is for BB92 and is available to fit 24mm cranks.
The pf41 is a press fit but like I have said mine is a threaded bb there lies the problem 😭😭
Well lit close up pic?
What is the diameter of the bb shell?
Unless I’m missing something can you not just use standard shimano BB cups with the (I presume there is one) middle tube from the existing BB?
If a manufacturer's used some damn fool standard they ought to be able to keep you straight on what you need. But it does sound like you just need a normal threaded BB, and a crank with a longer axle, sort of like fatbike and dh bikes
If I use the standard cups in the frame I'm at 108mm I was thinking fat bike cranks but don't fancy buying some and finding it doesn't work ,it was a new frame so no bottom bracket was included.
