[Closed] Pressfit 121mm B&B options?

Hi

Just trying to figure out which BB I need to run a normal 24mm axle crank in my carbon Beargrease. The standard fit BB is a Sram BB121mm which won't fit a normal 24mm axle crank as the NDS bearing is stepped down to 22mm.

The BB shell has an ID of 41mm, which is the same as the shimano Mtb standard.

I was thinking of just pressing in the shimano BB91 cups and leaving out the centre tube.

Has anyone fitted something like a race face, Middleburn or Surly HT2 style chainset to these frames? Is there a spacer in the NDS bearing I could pull out or is it actually a different bearing to the DS?
