Not sure what it is, think it's a combination of things, but that looks really cheap and nasty.
I don't suppose they are going to be pitching it against their Quattro's etc in price, so its possibly going to be a cheaper product. Wilier did a chromovelato last year which looked very nice as a frame but the bits were a bit of a mixture (same as that pinarello I think).
Perhaps its that Colnago has the name to pull it off for high end steel frames? (Apart from a lot of smaller builders of course). Not sure - I think the brake cable grips are a bit odd considering there are braze-ons for the gear levers. Still, would be interested to see one and the price.
