Ronno6, I'll probably PM you when the bike's ready to paint as that's one of the skills I want to learn.

I had my favorite shop knock out the stuck headset races and it was good to see some old friends. Two of the three housing guides and their pins survived removal, fortunately I have a spare guide. The weather is going to be iffy this weekend so I'll start stripping the paint.

Otherwise I'm just waiting on a reply about some parts for the build.

In 88 Cannondale had an exchange program - your old frame and 200 bucks for a new frame, or something like that. I ordered the new frame in the summer of 88 and it took a couple weeks to come in. Consequently I've always thought that frame was manufactured in 88. The color I'd originally wanted had been discontinued in 87, I think

Just looked at https://www.vintagecannondale.com/year/1988/1988.pdf
and it shows both types of dropouts in the catalog ... Oh well, at least they were a matched set - imagine having one dropout with an eyelet and the other without!

That same website has a section on decyphering the serial # to designate frame size and date of manufacture. That should clear up any question you may have as to year.

I'll be glad to help, however the Imron system I had used is no longer available. So, any assistance I cam render will be somewhat generic.
I'm glad to see that you are doing away with that (ugh!) Blueberry color, although I am building up a Blueberry (ugh!) ST400 in the 27" frame size as a training/group ride bike, and leaving the color for the time being cuz it is in good shape. (I just won't spend much time looking at the frame while riding!) Your Green sounds great! My favorite is a powder color called Blue Ice Explosion.)

Yeah, but I sold it around the turn of the century. Other than a couple pictures, the original headset, and the bb cable guide, it's long gone.

Ronno6, Thanks for the encouragement, I hope the green works well on a bicycle. I looked up the Blue Ice Explosion https://jacobcozby.fatcow.com/id11.html , very pretty and I also like the Wet Black at the bottom of the page.

How bad was the fork? It took four hours with paint stripper, sandpaper, a sharpened screwdriver, a die grinder and three different wheels and bits to remove the rust, that's how bad. Where the paint hadn't been molested, which was darn little, the steel was pristine. It's in two coats of self etching primer now.

For anybody interested the bare frame plus the down tube boss weighs 3.9 lbs.

Black is very pretty when it is done correctly. It takes very little orangepeel to mes it up.
I had a black 'Dale with Bianchi Celeste saddle, bar tape, cables and custom graphics. Looked great!
Your green is very reminiscent of the green used by Cannondale on their mid 90's touring frames.
It works just fine!

Ronno6, I had a '96 2.8 in Black Gold. There was a 10% gold tint in the clear coat and it was stunning, IMHO. It was too late in the year to order a frameset so I bought a R400 to have it. I have little style skill, but the black and Celsete theme must've looked good!

The self etching primer may not work with the Tange cro-mo fork, it just doesn't seem to be bonding well. And I weighed it also and it's roughly 1.5 lbs.

Brad

PS Thanks for the photo, I like that!

This is a real Cannondale R500 resurrection. What can you do when the derailleur hanger breaks off? Go nuts and do the undone.
Here's one of our latest projects at essentials bike works. These pics are not recent, our dropouts have been welded on and need some filing.

That looks to be a great solution.
Only other suggestion I would have had would be to have the original dropout machined to accept a later model replaceable hanger from Cannondale or another manufacturer. The Cannondale hangers would require machining to both sides of the dropout, as their hanger sandwiches the frame dropout between two tabs, then the whole shebang gets held together by a couple of 4-40 (or similar size metric) screws.
Other hangers would have needed machine work to the outer face.
That might have been a bit less costly than your route.
But, with your fix you will have an older model Capo !!
Are you not concerned with the welding causing a soft spot in the aluminum?

This is a really experimental project for us so we don't really know what is about to go wrong. Capo? is that a different brand or a Cannondale track model?

The Cannondale Capo, from what a quick search has turned up, was available for track or road. It featured that slotted, rearward entry rear dropout like your conversion.
Have fun!

Very interesting! As thick as the OEM dropouts are they maybe able to handle some heat and the heat maybe contained to the dropouts with dampened towels on the chain and seat stays to isolate most of the heat from the tubing. Several tacks with a cool off period in between rather than a single bead is how I'd try that. I have a replaceable hanger, which would require machining as Ronno6 described to install, as long as there's enough drop out left to machine.

The early STs really do look good, especially in the extra large sizes I think, most likely my next project.

Other than the frame and fork it looks like I'll only reuse the crankset. While the 52T chainring shows very little use, I did find one tooth that I had to straighten. The 42T held up pretty well when comparing it's tooth pitch to the 52T so it's a keeper for now, I'll know for sure after it's rideable.
