Here is my 1987(?) Centurion Ironman Expert that I purchased when new (I'm pretty sure it was in 1987). All original except for the seat, pedals and tires. Shimano 105 with Biopace. It was still my primary ride in 2011 when I did 1700 miles on it including a century. Now I have a carbon bike, so the Expert has been relegated to the winter trainer. I've thought about selling it, but can't bring myself to do it just yet.
