I'm the proud owner of '81 Centurion Super Elite that I converted to fixed gear (original paint, leather VO saddle, matching tape, tried to keep it classy). There is an Elite RS for sale locally and I'd like to find some more information about it before I pull the trigger. It has a 600 groupset with biopace chainring, aero levers, and black paint with a contrasting metallic silver seat and head tube. Can anyone tell me the year and if all of the tubes are Cr-Mo? I know the 84 only had Cr-Mo main tubes.
