Here's mine that I've had for quite a while. Almost mint condition, its been part of my collection for years, but I'm thinning out the herd and the frame is to small for me. Great riding bike, though.

You could add year range to the Craigslist posting. That's Shimano New 105, which was available 1987-1989 but this appears tio be the 6 speed version which was offered 1987-1988.

Thanks T-Mar! I will.

BTW...here's my Centurion Ironman Master...

Never get tired of the legend.

I've been riding the heck out it. I put some 28 schwalbe marathons on it and I couldn't be happier. I can see what all the hype around these vintage steel bikes is. It soaks up the road & bumps. The indexed 600 is great. I even like the biopace rings. I doubt this is the last vintage steel I'll own. Thanks for all the help/comments.

Well, my friend, now you know it's not hype. It's real. It's steel. It's the deal.

We are so smug, we forget to be snobs about it.
