See the original from the 1986 Bianchi catalog on bulgier.net.
While I usually go from classically-styled bikes, there’s something elegant about the curves of this design that just strikes me. It seems fluid and alive. It’s like the bike is as muscular as the sprinters who ride it.
I don’t believe this was ever really a production model from Bianchi, but that it was mainly in the catalog for upscale value. (Though I imagine they would make one for you if you were willing to pay Whatever They Want.) The only thing I could find about the C-4 Project is from theC4 company’s website:
“The C4 frames made their debut in cycling competitions in May 1987, when the Bianchi racing team took part in the time lap of the Giro d’Italia (Cycling Tour of Italy) equipped with fork frames designed and produced by C4. These frames were a world preview for some characteristic components, such as the entire carbon monocoque construction without joints, the frame without saddle pipe, the adjustable seat pin all dimensions with three unique frame sizes, and the carbon monocoque front fork.”
If anyone has any other info about these bikes, please post in the comments.
