I've been on Di2 for 2 years now and spent some time on an eps bike yesterday.
The components look like works of art. The shape of the shift lever/hoods, the shape and construction of the rear der, the profound use of flawless carbon fiber and the resultant shape of the rear der body puts the eps on another level entirely from an aesthetic perspective when compared to Di2.
I really liked the shape of the hoods. The texture of the hood covers are very nice and the shape felt great in the hands. I have always preferred the shape of the campy brake levers and this was no exception. Beautiful, smooth carbon levers, the best in the business- what else can I say about that?
Based on reports I had read, I expected a much more mechanical feel to the shifts than I experienced. I've always felt that Di2 has always lacked in the "click" and tactile feel that lets you know you are requesting a shift and I think the eps could have gone a couple of steps higher in that department. Don't expect a huge difference in the click that you'll feel compared to the Di2, it's still not firm enough in my opinion. If you could imagine sram Red as the benchmark as a 10 on a scale of a 1-10, and Di2 as perhaps a 2.5 (with 1 being no indexing at all), then eps might be a 3.5 or 4 on that scale. Still not quite enough feel in my opinion.
Now regards to the actual placement of the button/lever themselves- the lever is in the usual place and feels classic campy. The thumb button felt like it was in just the right place and the downward motion of the button moved in a very nice arc with plenty of travel. Shape of both felt as good as it could feel meaning I don't know if I would change a thing if I could.
If you think the front der on Di2 sounds "good", well, the eps solenoid motor makes an even more pronounced "terminator" sound. Lounder, and much more noticeable if you can imagine that. You are reminded with every shift of the front der exactly what it is you are riding.
Shifting was spot on and perfect with nary a hiccup. Just as promised, holding either shift button depressed resulted in multiple shifts. I expected actually a much more rapid sweep across the entire cogset after the slight delay after button press, but in hindsight, it's probably a good thing that it doesn't sweep across too many cogs too quickly. Moving across too many cogs too quickly could make it difficult to modulate and time the release of the shifter quickly enough to prevent a resultant too tall or too low a gear thus requiring further shifting to find the desired cog. I think with the current settings and enough time, one might be able to develop a feel as to just how long to keep shifter depressed to shift 4 or 5 or how ever many cogs at a time and be spot on.
The actual exactness of each rear shift was flawless. Not much more to say about that, perfect means perfect.
Front shifting was also about as good as it gets. I could not tell a difference in the shift quality going from small to big ring and vice versa when compared to front shifting on my Di2. Shifts were instant and with no hesitation or skipping on the ramps. That's saying something as my experience with the front shifting on my Di2 is about as close to perfection as I've ever ridden.
Trim on front der was automatic and reacted in much the same way as the Di2 front der. I'm fairly averse to cross chaining as a habit on my own bikes but I did ride the eps cross chained briefly and paid attention to the front der trim and it behaved just as one might hope-perfectly adjusting trim to prevent chain rub on the inside or outside of the front der cage.
If eps were available separately at this moment, would I ditch my Di2 to buy eps? Well, if it was within 20% of the price, I would. I'm not positive with regards to retail price, but I was told the group would be $6000 or thereabouts. That would stop me dead in my purchase tracks.
I'm one who has no issue with waiting for pricing on the newest products to come down to earth. My impression of buyers of high end recent campy product want something different as well as functional. You just can't compare the looks of mechanical super record to dura ace much less eps to Di2.
EPS makes Di2 look almost cheap and industrial next to eps. Satin (dull) grey aluminum versus shiny carbon fiber.
It would be unfair and difficult to describe Di2 as a corvette and the EPS a Ferrair 599 with contrast glove stitching on the seats, alcantara inserts and carbon adorning the dash surfaces.
Both ultimately do the same thing and in almost identical fashion. It's just that one makes you stare in awe and wonder and with admiration. At the risk of sounding too cliche, it's sexy. Oops, then you have to pay......
BTW, the shop owner whose bike I rode yesterday has a couple of the new Dogmas for sale with the eps. If you're interested, PM me and I'll get you his contact info.
great report, us Italians sure know how to make something sexy
