Once again Graeme, thanks for chiming in. As soon as you mentioned “eps”, I looked back at the title of this thread and said to myself in Homer Simpson style “D’oh!”, because my earlier post on the chain was in reference to mechanical 12sp only, and for EPS the chainlength and adjustment is indeed different, and is the same as for 11sp, using the small/small method that Campagnolo has used previously up to 12sp mechanical. In fact, the eps 12sp rear derailleur is much more like a slightly modified 11sp dérailleur than the mechanical 12sp dérailleur in its setup and operation. The mechanical version is truly a new beast in its own right. EPS 12 still uses the “H” screw for adjustment. There is no “H” screw on the mechanical 12 version and the linkages, geometries, spring tensions and appropriate chainlength all combined with the B-screw adjustment allows one to adjust the mechanical version far more effectively than the EPS version. EPS also doesn’t use the “joint” between the regular hanger and the upper main pivot. I don’t think there’s any way you can adjust the EPS derailleur nearly as close to the entire range of cogs (biggest and smallest) as you can get the mechanical version to be, and this makes the new Campagnolo mechanical 12sp rear derailleur the crispest and most precise shifting rear derailleur on the market today in my opinion when set up properly.
Also, to the OP or anyone else looking to install this stuff on their own, I agree that the Campagnolo videos are probably your best resource. The little nuances, tips and tricks etc., will come during those ah ha moments that you must actually experience to truly understand. One thing about the videos that shouldn’t be overlooked, particularly if it’s been awhile since you’ve done a complete new install with the new stuff is that they kind of assume you know and understand the info in the preceding videos leading up to it. For 12sp setup videos for example, consider an understanding of the 11sp setup videos a prerequisite if you will. So if in the video they mention something like “this part of the setup is the same as for 11sp, except for the following...”, make sure you understand the 11sp part they are referring to.
Happy setup!
