I would like to convert my BB PF 92 to a threaded one (something like this) but wanted to make sure it would fit. The crank is a SRAM NX so im pretty sure the spindle is 24MM stepped down to 22MM. the Bike is a 2018 fuel ex 9.7 carbon. For my sanity...is PF92 different than BB92?

I strongly suggest a thread together bottom bracket for a press fit shell. I initially used a regular Wheels MFG bottom bracket in my BB92 Fuji but replaced it with a Wheels MFG thread together version after persistent creaking issues.

this is the one i was hoping to get https://wheelsmfg.com/bottom-bracke...contact-bb-for-24-22mm-sram-cranks-black.html

i was hoping to verify it would fit my trek since sometimes they have some uniqueness to them and it says on my Frame PF92 and none of the BB's on wheels say they are compatible with PF92

My bike came from the factory with the Praxis thread together press-fit. In the last 3.5yrs of beating the shit out of my bike, putting it away wet, not one sound from that bottom bracket.

i think the answer they are the same. PF92 is the Trek naming convention for BB92

I have a WheelsMfg threaded/press fit for my Enduro. They work great. Regarding the fit question for your bike, recommend giving WheelsMfg a call, or email and they will confirm for you.
