I canβt use 11sp. I specifically want 12sp because the chain line is different between 11 and 12. The only reason I want new cranks is for that reason.

they moved the chain line out with the 12 speed cranks to mimic the spacing of their 11speed disc brake specific crankset. with enough dikking with it you can get it work perfectly in the stand probably and maybe even out on the road if you're using small chainrings and your bike has longish chain stays. but as soon as stuff starts to wear- or if the chain gets a little mucked up- or you shift like a jerk under load pr any number of other not nice things- the bike is going to be far less likely to shift smoothly. you'll also almost certainly get some rubbing on the big chainring when the chain is on the small cog in the little cogs on the cassette and the chain will be more prone to falling off too.
it isn't the width of the rings that is the problem- although they're not correct either- it's the chainline. modern drivetrains work super well-but they are sensitive to chainline. the new campy stuff works flawlessly- and i'm sure with the wrong crank the eps stuff is fine for some people...but in my experience of building a bunch of campy bikes both 11 and 12 speed and trying to make weird stuff work together- i wouldn't let a bike out the door of our shop with that set up without telling the client that it was at best a B- application.
ps the mechanical stuff is somewhat more tolerant of wacky setups like this- as are bikes with small chainrings and long chain stays. the worst set ups are bikes with big chainrings (53/39) and sub 420mm stays. Those bikes eccentuate an already out of spec chainline and the results are that the bike doesn't really work in a bunch of gear combos it should work in.
This fork has been a game changer for this bike. Already sold the Enve that it replaced. Bike feels way more enjoyable to ride now. Way way way more balanced. The frame/forks compliment each other so well. Way better than the frame was with the Enve. Seeing it flex as it goes over bumps is a total joy.
Feel like Iβm almost there now. Need to go back to an 8Β° stem and new wheels turn up soon. Then I think it might be complete. Other than Chorus cranks. Need those too.
