Robbie I have a pink 87 Ironman and it's a 56cm just like that one. I had a mint condition 60 cm one I sold for $350 12 months ago and bought the one I have now the same day for $100. They seem to come up around here on CL about one every three months.Most are to big or to small. Mine has 600 on it not Bio/105 combo.
