My wife has what we believe to be a 1990's Bianchi that she bought used in 2000 or 2001. I can't figure out what it is...but have seen awesome responses on these forums, so I figured I'd ask! I'm a noob on here, so can't post a picture, but the bike has carbon front triangle with metal lugged joints. The chainstays and seatstays are carbon as well. The seatstays come together into one piece above the rear brake caliper, and it's labeled as a "Cobra" system. The front fork may not be OEM, but is carbon and labeled "Hydra". The frame has a "Paradox" label on the top tube, and the seat tube has a Superset II label frame and a small Campioni sticker near the top. It's a 1 inch steerer, and came with a Campagnolo group. The color is raw carbon fiber on the tubes and a dark purple on the joints. Let me know if more info would help! I appreciate any help you might be able to offer...after days of searching all of these terms I've come up blank! Thank you!
