Serotta Coeur d'Acier - American Engineering of Steel & Cycling Art

https://mybikething.com/home/product/... The Story Behind the FrameSerotta Colorado C4 - Serial #CCD52136 - Coeur d'Acier "The Heart of American Steel" This isn't just any steel frame - it's built with Serotta's proprietary C4 steel, their Colorado Concept tubing system developed specifically for discerning cyclists. Ben Serotta engineered this premium steel alloy for riders who demand the ultimate: precision-crafted tubes that deliver the legendary steel ride quality while meeting the performance demands of serious cycling. This represents decades of Serotta's framebuilding expertise distilled into their proprietary tubing technology. The Ride Serotta's proprietary C4 steel delivers that legendary connected-to-the-road feel and climbing efficiency that serious cyclists crave, while the carbon wishbone seatstays add vertical compliance for all-day comfort without sacrificing lateral stiffness. This mixed construction gives you the best of both worlds - the buttery smoothness and power transfer of premium steel where it matters most, with carbon's vibration damping exactly where you need it. The result is a frame that flies up hills and eats up centuries with equal enthusiasm. Material: Columbus Colorado CS4 steel main triangle with carbon wishbone seat stays Made in USA craftsmanship Serotta's premium steel/carbon hybrid design Single piece machined chainstay and dropout - stronger and added  road damping. The wishbone carbon fiber seat stay is molded into a single piece, wishbone design, and curved to absorb road noise. The carbon is capped on both ends to steel. At the dropouts, the steel cap is bolted to the dropout. This unique construction notes the craftsmanship and detail that most will overlook. Why a carbon seat stay?  You can't shape steel like you can carbon. The wishbone design allows the carbon seatstays to filter out unwanted road harshness while preserving efficient power transfer. The curved geometry and carbon construction work together to reduce high-frequency vibrations (road buzz) that cause rider fatigue, while maintaining the lateral stiffness needed for responsive handling. 1795 grams (3.9 lbs) Year: 2000-2002
