As far as I can tell this is how the bike left the shop when new. The Date codes on the brakes, bottom bracket spindle and cups, cranks and derailleurs all go to 1989 and range from January through September. So we have a late 89 or early 1990 bike and group here.

I don't recall the saddle, it was damaged. The handlebars were severely grooved and gouged from a set of loose aero bars. They were bad enough that even I questioned their safety and replaced them immediately.

Present Gear:

At the beginning of this blog we are starting with all the above components, except for the bars, stem, levers and pedals. The levers were replaced with Sora Brifters in this bike's brief turn introducing me to cyclocross. Along with the brifters went an "ergo" handlebar and of course another stem because the Cinelli was the wrong size.

Here's the plan:

Clean up and reinstall all the original Shimano group. The brake levers have some damage and I don't think I will ever find the broken little plastic piece that fits between the rubber hood and the lever. The white hoods are trashed. I will probably replace them with some other aero lever. Possibly the Tektros because they're comfortable or something period correct that looks good. I'm a bit torn.

The Headset will need to be replaced. It has almost never been adjusted correctly, or stayed in adjustment and has a center detent. It will probably get a Tange Levin unless a nice Dura Ace or similar falls my way.

The brakes were my first dual pivot caliper brakes. I was immediately impressed by their bionic crab claw looks and bionic crab claw grip. I'm not sure if I'm going to like that look for the future, but they are on there now and they still work great.

The ugly and heavy seatpost will be replaced with an "Aero" seatpost that is on its way to me now. It will get the full polish treatment as well.

The wheels are true. The hubs and bottom bracket only need cleaned and greased. The old D/A 7400 Bottom Bracket is a marvel. I've got two of them and both have run perfectly for many years.

The components that are in rough shape will be stripped and/or de-anodized and polished. I'll have some progress photos of the cranks, handlebar and stem tomorrow.

The Frame:

The frame will be the subject of a future post. So many possibilities and limitations. Some decisions I'll have to make as I clean it up and evaluate just what is possible.
