Someone told me i should buy a cheap screw in pressfit bb but swap the bearings. How would i do this? I know wheels mfg has one for like $200 but can someone throw me an aliexpress link if theyve done it? Thanks

Also, taking recommendations for bearings to replace it with.

You'll want a tool something like this or this. I can't vouch for either as I haven't used them although I'm planning to buy one to do the same thing.

I just used a 1/2" extension and a hammer to get the old bearings out, and a big enough socket to get the new bearings in.

When nothing else is available, a flat screw driver or a 8mm Hex key and a hammer can do the job too.
Just hit gently over the whole circumference of the bearing.

If the bearings is too far, it may disassemble(with a press too), leaving the outer race only in the frame.
Although more challenging a hammer with a flat screw driver can get it out.
