Any prices for Chorus EPS?
I'm surprised at the discontinuation of Athena EPS, that was the one aiming at the "cheap electronic" price point, i.e. Ultegra Di2.
Will they sell Chorus EPS at Ui2 price? I seriously doubt it...

I saw one site that said Chorus EPS is priced at $3500 USD full retail.

Assuming 50% off retail, it would be $250 above Ultegra Di2. Holy cow!

I think it looks better on the bike that in the conceptual photos. If they keep the logos subtle it may just be ok. Could be a grower we shall see!

I love the new groupset, does anyone know when will Campagnolo release specced weights, prices and delivery times?? Im in the middle of a build and I would like to be one of the groupset early adopters =)

I really hope they didnt increase q-factor.
Also, can anyone explain how a 4 arm can be stiffer than a 5 arm? Stiffer chainrings are always welcome but wouldnt one more arm be even better? Just wondering.

I think it has to do with the wider arms and asymmetric nature of the system... I can't feel any significant flex in the old 5 arm system...

I think overall spider stiffness isn't generally an issue, I think that it's the arm/spindle area that does the most flexing. Therefore four arms is all that is needed for the rings, and they can use the extra carbon to increase area/ material in higher stress areas while maintaining/lowering weight

So Centaur is going leaving Veloce as the sole 10 speed group and the only change to Veloce is the redesigned downshift lever?

If that's the case I might stock up on a couple of cassettes, as the Centaur design in nickel plating with alloy carrier is superior to the zinc plated Veloce equivalent.

The veloce and athena has the redesigned thumb lever like the eps models and they will also update the chainrings with the same profile as the sc-14 chainrings found on the super record rs.

The centaur cassette will still continue to be produced. Only the components are discontinued from the lineup.

I don't think its a question of stiffness since the actual crank is one of the stiffest available. I think it has more to do about chainrings swapability compared to the old crankset. Its easier to do a crank that can accept compact and regular chainrings with a four arm design.

The reason they have went 4 arm is the spiders support the chainrings at the point where the greatest force goes through the chainring during the pedal stroke.

Pretty sure it's more to do with chainring compatibility. The lack of a spider arm at the dead spot on the pedal revolution is just the result.

If it was all about compatibility they all could have went to compact 110bcd ? The fact Campagnolo is using 8 bolts it therefore appears they have a different bcd for the inner and outer rings where as Shimano uses one standard for both rings means at the very least the outer(or inner) rings will not be compatible. Campagnolo have never made shimano compatible rings, even their 110bcd compact contains 1 bolt that is not set at 110, making them only compatible with Campagnolo. I would imagine that Campagnolo realises that this design is a better engineering solution, supporting the chainrings where it is under the most load, might have the benefit of being able to engineer lighter rings and losing a fifth spider to lighten their cranks.
