Cannondale Cujo 1 (2018): 12-speed drivetrain

I successfully mounted components of a 12-speed drivetrain on my Cannondale Cujo 1.

Mounted components:

Shimano Deore XT BB-MT801: Bottom bracket - The stock FSA bottom bracket is worn out and needs to be replaced.

Shimano M7100-1 (SLX): Crankset 175mm with 32T chainring

Shimano RD-M8100-SGS (Deore XT): 12-speed rear derailleur

Shimano SL-M8100-R (Deore XT): 12-speed shifter

SunRace CSMZ903 WA1: 12-speed 11-51T cassette (for HG)

SunRace CN12A: 12-speed chain

My first impression is positive. Everything works well. However, I would prefer a 34T chainring. The front 32T and rear 51T are too slow for my needs.
