EDIT: Got some history on the frame now. Possibly a 89 model.
The Centurion Dave Scott Ironman Carbon came out in 1988 only, and was
shipped with Dura Ace 2x7 components. Very few have ever gotten far with
the components. I've seen a couple that still had the crankset, and none
with the headset. I suspect the headset was always Shimano 600 (6400
series) The hubs were laced to Araya CTL-700 rims, the seatpost was a
smooth 25.4 and the stem/bars were Nitto.
The Centurion Carbon is not nearly as well known, and may have been an '89
model, or an overseas model. Domestic US distribution of Centurion models
ended in 1989, with a couple of Diamondback/Centurion models sold with two
logos as late as 1991, but no later.
European licensing seemed to extend for a couple of years after that, I'm
The font and decals on the Carbon indicate a likely 1989 model. The
graphics are consistent with 1989, and unless it was a non-US model, that
would be the highest likelihood. The Carbons (and I've only seen two) came
with Shimano 600 components, also known as "tricolor," the 6400 series. The
frames, other than graphics, are nearly identical. I've owned 3 of the
Ironman Carbon models, and none had Tange on the frame anywhere, but they
did have Made in Japan on them. The fork was all aluminum, polished, and
had Tange on the fork decals.
So, my best guess is 1989, and my take on the original components would be
Shimano 600, the 6400 series. I don't know when RSX came out, but 1991
comes to mind, which would likely be long after production of these frames
My plans are to keep everything as is. The clear coat of the carbon is suffering from UV degradation, so Ill remove the top coat, and will be recoating. The decals are stickers, so they'll be removed, and then scanned. Now I need to find a vinyl/sticker printing service. Any here able to do it? Or know someone who can? The RSX groupset will be overhauled, and then reinstalled.
Received it this arvo! Took it out, and stripped the last of the components off. Bare frame here
Bottom Bracket with an integrated cable guide. Does that 59x64 mean the angle of the tubes?
Some pics in the sun to see the carbon weave!
And serial number on rear dropout. Looking around, everyone says its on the BB, but as you can see, its not there, but on the dropout.
Anyway, decals have been removed, and Im in the process of scanning, and creating a file for someone to print.
Tomorrow, I will begin to strip the top coat. Once thats done, all the aluminium lugs and fork will be polished to mirror!
