Photo: Danilo Di Luca's De Rosa King "RS". cyclingnews.com reported, "Danilo Di Luca's (LPR Brakes-Farnese Vini) new De Rosa King 3 RS is supposedly 15 percent lighter and 18 percent stiffer than the current King 3 by virtue of an upgraded carbon fiber mix and new lay-up schedule. Based on the current King 3's claimed weight, that would put Di Luca's frame close to the 800g mark though it's unclear at this point when this upgraded model might be available to consumers. Otherwise, Di Luca's King 3 RS bears close resemblance to its standard King 3 cousin with the same seatmast head, two-piece aluminum dropouts, internal cable routing and smooth lines."
