The Shimano 11s to 12s compatibility thread
Moderator: robbosmans
Let’s have a separate thread about what can or can’t be combined from 11s to 12s. Not limited to Di2 parts but also cranks, shifters, calipers, freehubs etc. Maybe we find some users that have early access to 9200 and 8100 parts that can do some tests?
Early speculation is that 11s cranks and chainrings should be compatible with 12s chains and cassettes since many are already using 12s XTR chains on their 11s cassettes and chainrings. What else?

CyclingNews says the rim brake 9200 shifters are just rebranded 9100 shifters... which suggests that 9100 di2 rim brake shifters are compatible with the 12spd derailleurs (unless software locked out of it). This is interesting to note because it would make 9100 shifters & RD with 9200 FD be the most WW di2 option, though by only a mere 8g or so.

Anyone knows if the 12S chainrings uses the same BCD as the previous 11 speed?
Would be great if I can back my spider based power meter.

Compatibility charts are here, though lists little cross-compatibility:

re: cranks
after a bike company *once again* has decided what's best for us (in short: 53/39 cranks are a no-no) for dinosaurs like me the only way to continue on a same setup will be buying cranks from a different producer
I get it, they gotta make us buy more. after all, given how we've devastated this planet, we've only got so much time left to do "business as usual". carry on!

Use your current cranks and buy some third party chainrings. Or step up to 54/40 since you’re a manly man and the extra sprocket means more range with similar gear jumps. Or use your current rings because chances are they are going to work just fine.
making a change only for the sake of making it - 53/39 has been, and frankly speaking still is, at least amongst those who race, a golden standard. I bet they've produced tons of marketing BS as for why 52/36 or 54/40 is "better" but the thing is - it's different. doesn't give you any edge, any new 'features', just makes you adapt to a completely new gearing.TobinHatesYou wrote: ↑Wed Sep 01, 2021 7:44 am

Shimano said on the Marginal Gains Podcast that the pros are asking for 54/40. 52/36 is for the mortals. Or you can run 11-34 with the 54/40.
