you will regret the fact that you converted a centurion into a 'fixie'
suggestions for paint colour.... purple with white sparkles powder coated and have a centurion decal put back on the top coat then give 3 layers of clear liquid coating to bring it back to life... then put on 6 speeds onto that bike and some old shimano arabesque 600ex /dura ace ex or some old campy c record groupo...
