2020 CUBE 140 HPC SL GEN 4 - Had my rear SRAM mech disintegrate and cause damage to my rear block so decided to replace it all with XTR. Some of you may already know this, but it was all news to me. No.1 Shimano now only make blocks to fit their micro-spline hubs. If you want to use 12 speed shimano components on a std hub you'll need a sunrace cassette or similar. No.2. The Gen 3 lock ring tool does not fit the gen 4. Have tried two separate tools both do not fit. There is apparently now one for the gen 4. N0. 3 The SRAM chainring looks like a bespoke piece. There are no replacement chainrings that I can find that fit the gen 4 motor spline. The only way to do it, is to purchase a gen 4 spider and then fit a standard 104 - 4 bolt chainring. I can only find the spiders in europe and not the UK. I know this is a 'new' bike but thought these things would already be in place. Even the guy at Bosch seemed confused.
This is just notice in case any of you decide to change drivetrain components so know what to look out for!
