Thks Phat & Koffee .. and just for the record, I don't have the $ to by a Dogma .. although I am quite interested about the fact that an entire team had to return frame but this could be related to multiple causes. Mg alloys are regularly used in the high end automotive industry, aviation etc .. and once properly coated should be fine. Pinarello uses a variation of such an alloy produced by dedaccai and I would not consider them specialist or inovators in this field but rather co. just sticking their label. Mg alloys are known to be super light (extremely low density approx =1,80 g/cm3 which allows to produce a frame with higher dampening properties and rigidity for the same weight .. I am not by any way defending the use of Mg but have yet to find a major problem for their use .. pls keep this thread running .. we will eventually find something .. Cheers
