I'm in the process of stripping and rebuilding my 1996 Bianchi Reparto Corse cyclocross bike. Lugged steel, Dedacciai zero uno tubing. I took the fork off and noticed some cracks in the paint at least on the underside of the crown roughly around where the steerer tube circumference would be. See pic. Is this a sign of damage or nothing to worry about? I can take it by a frame builder but I thought I'd post it here too. Thanks - Colin
