so 2015 RDs are no longer for sale so this means all new mechanical models will be HO.

no mention of HO Tech here: https://www.campagnolo.com/US/en/Compon ... derailleur

only info i could find was on https://www.bike24.com/p2229836.html which says:
"The HO version of the Chorus rear derailleur has been especially optimized for disc-brake frames with with 142 mm OLD. The derailleur mounting link and its design has been adapted to provide an easy mounting and dismounting of the thru axle or rear wheel. Furthermore the teeth of the upper pulley has been extended to guarantee precisely shifting also at high skew."

¿anybody seen these in the wild and can make any comment?

*according to 2018 price list https://www.campagnolo.com/media/files/ ... RP-ENG.pdf

Is the ‘PO’ here a typo?

PO is short for potenza

But HO potenza is typo

That is very good news, perhaps contrary to my expectations.

Hi graeme_f_k

Just when I see you on the forum, any idea if the new 12sp EPS levers, whenever they appear, will be in any way back compatible with the existing EPS 11sp derailleurs? If not it's going to be extremely expensive for existing EPS users to move up to 12 speed. Also will the 12sp EPS be compatible with the existing V3 power unit and interface? Ta.

If he knows he's probably embargoed from telling you that, lol. But I can't see how the existing V3 interface unit for 11sp will be able to drive EPS 12 speed. Besides, Campag may want to shrink the interface unit so it can be inserted into those little cupboards that are beginning to appear on frames.

wwnick, I just did what you are asking about. I replaced a 2015 Record derailleur with an HO medium cage. I can't really see the difference, but it works perfectly.
FYI, the medium cage works as well (or better) as the regular cage on all my cassettes.

Just occurred to me that it's all probably immaterial - the new EPS 12 speed may well be wireless??!
