Testo: <blockquote data-quote="Dogmafpx" data-source="post: 1682213" data-attributes="member: 4239">Qualcuno ha letto l'articolo del sito <a href="http://bicycling.com/blogs/thisjustin/2009/07/08/pinarello-dogma-60hm1k/" target="_blank">http://bicycling.com/blogs/thisjustin/2009/07/08/pinarello-dogma-60hm1k/</a>oltre a vedere le Foto?Viene ripotata la tecnica di progettazione e costruzione del nuovo telaio, dovrebbe pesare 840 g ed essere il 23% piu' resistente del Prince.Questa parte mi sembre interessante:"Pinarello has enjoyed a close relationship with carbon supplier Torayca: Pinarello had exclusive use of 50HM1K in the bike industry (used in the Prince and several Tri/TT models) and, with the Dogma, Pinarello now has exclusive use of 60HM1K: which, not surprisingly, is claimed to be a more rigid material than 50HM1K: the rigidity is 60 tons per square centimeter, instead of 50 tons per square centimeter. Usually a higher modulus and more rigid carbon is a more brittle, which probably explains the next bit of info. 60HM1K has what Torayca calls Nanoalloy which is described thusly, Nanoalloy disperses nanoscale elastomers between the carbon fibers. These elastomers have the ability to absorb impacts and prevent the propagation of cracks as they occur. The result: Pinarello claims the Dogma frame weighs about 860 grams, 40 grams less than the Prince but is 23 percent more resistant to impacts."</blockquote>
