The all-new Cervelo Rca is the latest from the brand’s California high-end development center. It weighs about 670 grams in a size 54, and drops into the 500’s in small sizes. Most impressively, though, is Cervelo’s claim that the new frame is 7.4 watts quicker against the wind than the old R5ca. Photo: Caley Fretz | VeloNews.com
