C4 was founded in February 1986 in order to create and build carbon fibre projects by engineer Marco Bonfanti. C4 had always used its own system of moulding the carbon structures: NJC – No Joint Construction, which enables the building of hollow structures without joints.
C4 had such an innovative design solution that from the offset they were asked into a collaboration project with the renowned Bianchi Reparto Corse department. In 1987, the Bianchi racing team rode the time trial stages of the Giro d ‘Italia on bikes designed and built by C4. These were a world preview of the special feature monocoque carbon technique.
In the year 1994, C4 was the primary sponsor of the professional cycling team Polti, including Gianni Bugno and Ivan Gotti among others. Team Polti would be found riding the C4 Air One, a light, elegant and progressive example of Italian design. Our example is equipped with Campagnolo parts and runs on Ambrosio Excellence rims.
ConditionUsed. The bicycle is in good condition. The frame has no cracks, no dents and is not bent. The paintjob has been professionally refurbished and thus in top shape. All parts have been checked and are working fine. The bicycle went through a full checkup at Steel Vintage Bikes workshop! All parts were disassembled, cleaned and re-assembled again. The frame was checked for structural integrity and wearing parts were replaced with new ones. You can expect the bicycle in fantastic riding condition and ready to go for your vintage bike ride.

Just bought a second vintage classic bike from Steel Vintage. A great bike at an excellent price and they couldn't have been more helpful. Their fantastic service was every bit as good as before.
Placed the on-line order late on Saturday evening and the bike was delivered to me here in the UK the following Thursday morning.GB
Geeky Eroica Cool. I bought the "old-school" Italian made bike shoes. They were delivered in good condition and in a quick timely fashion. They're geeky cool, just like I hoped and they're put together very well (stitched nicely, no glues where it shouldn't be) light and fit properly!US
Steel Vintage Bikes are such an excellent company to deal with. They are passionate about vintage steel bikes. They have in my opinion very fair prices and very obliging to deal with. Packaging is great and no hassle even for delivery way down here in New Zealand.NZ
The overall service provided by Steel Vintage Bikes is always first rate. Delivery and packaging is always timely and well done. I cannot fault Steel Vintage and have been a customer for a number of years.. Plan to get to Berlin hopefully in the near future, stop in for a some Kaffee und Kirchen and a bike geek mooch around the shop.IE
