My understanding is that the Cadex was one of the first bikes to utilized carbon fiber tubing, I believe it's a 92. I bought this one to use the very nice 105 group on another bike. You might be able to figure out what model bike it was by the non-matching celeste bar tape that I left on because it is practically new cinelli cork. Hopefully, it's not too distracting. The 105 group includes brake, hubs, F&R D, 7 spd Cass., SIS DT shifters, brake levers, crank & BB. The post, stem, & bars are SR Sakae. The headset appears to be a Tange Vantage. The seat is a little scratched-up San Marco. The rims are rock solid Wolber GTX and tires are a little worn Conti Ultra 2000. It has new Jagwire cable and housing. It shifts great and rides fine. I want to sell it, but really don't know if these bikes have much value. What should I be selling it for?
