Thanks for posting all that goodness Barndoor. I super appreciate it! Aside from being newer I'd say our frames are pretty darn close minus the seat cluster........I'm really thinking it is a Proteus.
If only I could find a pic of another bottom bracket shell like mine.

Thanks again!

What's that blue tint (it bothers me, aesthetically)? or it's a just a reflection of something?

Probably just a reflection of the sky or the lighting.

Yes, that is definitely a Proteus. I can even tell you that it was built by Jeffrey Hall. Proteus was originally Proteus Design Bicyles. The cut out coulld either be considered two P's or a Pd. The frame was chromed at Amos Judd in Baltimore, probably no longer in existance. Chrome bike were very hard to do. Whereas paint fills, chrome shows every imperfection.

Well, there you go, kpug. You can't get much better info than that.

now you all can head over to my thread and help me identify my all-chrome mystery bike

Thank you sooo much! I'll try to hunt the owner down and let him know. I really appreciate the info!

That looks like the cluster on my chromed mystery bike. https://www.bikeforums.net/showthread...highlight=bike


Not much else looks the same except for the Campy Dropouts. Mine has a Cinelli BB, fork and lugs. My bike is probably ten years younger than yours given the rest of the kit. Do you suppose I should be looking at later Proteus work to find its home?

Yes, it is a Proteus made by Geoffry Hall. I had earlier misspelled his first name as Jeffrey. More then likely chromed at Amos Judd in Baltimore.

Thank you sir. I've been trying to figure out what the bike is for ten years.

Can you give a good guess on the frame tubing? It has a 26.8mm seatpost. Which with all the Italian stuff led me to think Aelle R. But Proteus would've been Reynolds more likely.

To answer that question or at least take a better guess, I need t know the height of the frame. At Proteus we used mostly Reynolds, some Columbus and occasionally some straight 4130.

It's a 60 x 58.

Whichever tubes were used, they're right. Reasonably light, comfy, rigid and perfectly stable on high speed downhills. Not all frames my size can do that.

Update. The steerer tube says "Reynolds 531 Butted 16/13." The BB is 70mm Italian.

Yes, I would agree that your frame is Reynolds. It's been a long time, but my eye caught the crimping on the chainstay. I would guess that your chainstays are actually Reynolds track blades. We often did this substitution because they were a gauge heavier and added significant stiffness to a frame and very little weight. Whereas the regular chainstays were shaped at the Reynolds factory for chainwheel clearance, we had to custom crimp the fork blades for clearance.

Those chainstays are beautifully conceived, elegant and sleek looking and still having plenty of clearance for cranks, cogs and heels. Thanks for the information. I'll be posting this all to my lame blog as I go.

I'm a little distracted by the chrome plating. I believe we had a few of these done but don't recall. The seat stays (ears) sure look like Geoff's work. 3 things to look for:
1. does the fork tube penetrate all the way down to the bottom of the crown?
2. when you look through the bottom bracket, can you see that the down/seat tube go all the way into the bottom bracket or they only partially inserted and brazed.
3. look for a serial number stamped into the bottom bracket. Other proteus' would have a similar pattern (e.g. 01234-7-22-11_01).

this is a gem because the finishing on a chrome plated bike has to be excellent; scratches from 500 grit sandpaper show up.

One of the owners (nickname Shoe Man) would almost definitely know.
