I still have my Campy C Record equipped Rosin, made for me in the early 90’s. And, my custom built Albert Eisentraut frame with all Campy Super record converted to titanium spindles and bolts. It helped that I owned a bike shop for 20+ years. I raced road bikes since I was 15. Rosin is Columbus tubing, Eisentraut is Reynolds. Both were great bikes and won a bunch of races... waaay back when.
