PF GXP BB - swap to Shimano?

2017 Liv Lust with GXP X5 2x crank (165mm) and Press fit BB with 'Pressfit GXP MTB PA + GF stamped on it.
I'm struggling with rings and bolts for the crankset - it's not playing nicely with the rings (non SRAM) and it needs new Uber short SRAM only chainring bolts (£25). It also needs new BB.

So, while it needs it all doing I'm thinking of going over to old reliable Shimano.
Can I just get a Deore Crank and Shimano pressfit BB?

I'm also pricing up going 1x as well, but that spirals in cost....

Should be fine.

Merlin have a Ninja pf30 bb for £30 that plays nicely with 24mm Shimano axles. Just fitted one to an Enduro without any drama. It needs an external hollowtech 2 bb tool to fit.

But I thought bb30 was different from PF GXP MTB which is PF 92?

Ok, different spec to mine then. Wheels Manufacturing will do something NICE with a price tag to match. There might be a compatible Ninja one too. Seem well made for the money.

Pressfit GXP and shimano are the same other than the NDS bearing on the GXP is something like 22.4mm ID as opposed to 24mm for the shimano.

Just smack a new HT2 pf bb in there and insert your shimano crank of choice
