A novice question and do forgive my ignorance – I’m new to modern bikes and this is the newest bike I have ever owned.
I am used to working on threaded BBs. But this is a PF of some sort. 68mm shell. I believe PF30.
But what are the teeth in this photo? Is this a threaded bracket? How do I go about removing it?
Thanks in advance for any help you can give.

What makes you think it’s press fit? I can see the splines for your bb removal tool in the photo.
I assume it’s a standard bsa threaded shell, could be square taper based on what we can see of the axle, but if you remove the crank arm bolt and look in there you will know for sure.
Square taper BSA.
The teeth for notches for a square taper bottom bracket tool.
Looks like a threaded square taper to me. Not sure what makes you think it’s pressfit.. looks like a bbt32 fits it to unscrew it
I’m an idiot – you’re correct. It’s a square taper BB. Thanks everybody.
