Could you identify which Ironman years use proprietary odd ball Shimano shifter braze-ons? Clear details about this still allude me.

That would be only the 1985 Ironman. The 1984 Centurion Comp TA also used that proprietary shifter braze-on.

Shimano called it the Brazed-on A Type, the standard shifter mount in use today they called the Italian Type, and the aero shifter mount that screwed into the top of the downtube was called the Brazed-on B Type.

I think adding freewheel cog numbers would be very helpful to those trying to return to stock.
Sidenote : Nobody needs to be concerned how I know what fingernail polish to use. Hah.

OK, folks. Please do me a 5-minute favor.
Look over the "main" information posts (Predecessor, etc)
Find the typo's and anything incorrect, or what you think needs changing.
Copy and paste the thread into a PM, and either add correction at the bottom, or in underline.
I'll look at each PM, correct the post, and we'll see how close we can get.
The gist is the OEM information, and touch-up gouge.

I'd like to see any OEM numbers on gearing, as well. I know the GPX was 52/42. I know the "round" Shimano was 53/39. I've seen different versions of the BioPace, both in 600 and 105. It would be nice to somewhat clear that up. Also, rear cluster info would be welcome.

You've got me thinking about another Dave Scott now. There are two for sale locally that look to be in great condition. One is desirable (by me) Miami Vice paint in 54 and the other is Red/white in 56 Has anyone found a definitat ive geo chart for these? I assume 54 = 54cm top tube and 56 =56. My preference in modern bikes is around a 545 top tube and 110mm stem so I'm really trying to see if I can make the 54 work for me because that's probably the smaller end of my fit


Edit: just saw the link to the spreadsheet. Awesome work Robbie

The Bicycling review of the 87 says 13-15-17-19-21-24, but I'd be inclined to go with a verified original bike; the test bikes could be specced differently from what hit the stores.

And that's what mine came with. (13,15,17,19,21,24) model number mf z012.
Unless you're the original owner or aquired the expert 87 from the original owner and asked what original parts have you replaced (for my own records). It would be difficult to verify what parts are original.

The first '87 to pass through my hands (now in Jim Muller's barn) was 13-15-17-19-21-24. The second lacked wheels, but both were 52/42 Biopace.

Re: you 88 Purple Haze

Do you know what the original cassette was on yours? I have two, but I don't know which is the original one. One cassette is 12/13/14/15/17/19/21, the other is 13/14/15/17/19/21/23. I imagine the Expert has the same gears.

Like you mentioned in the other thread, the front wheel is 28 spokes, while the rear is 32 on my 58cm frame. (that's new info RT)

Lastly, you mentioned some touch-up solutions for the purple parts of the frame. Any luck matching the off-white color?

13-14-15-17-19-21-24 (7 speed). Not sure about the expert.
28 spoke front 32 spoke rear for my 52cm. I know at some point the larger sizes jumps to 32 front 32 back. I'll check to see at what size that happens.
And lastly,the white yellows at different rates for everyone,So.
One thing, on that purple haze, it has a purple tinted clear coat that is so cool,but hard to match. Later.

Went back and counted the teeth on the cassette I have installed, and it matches. I must've miscounted before. I'm sure the Expert is the same.

I haven't been able to make a good match for that white. Lots of rectified rust issues on the top tube cable guides and seat tube lugs.

Not sure if this would be of interest to you, but as promised: The 88 master had 28 spokes front wheel and 32 spokes on rear wheel 48cm-58cm and 32 on front and rear after 58cm.
Probably should send that to RobbieTunes.

Very Nice spreadsheet. I have been lurking her for some time because I have an ALL ORIGINAL 1986 Centurion Ironman Dave Scott MASTER....Yes 1986. At least the serial number would indicate it is a 1986 (N6M....). With that said here is what this 29 year old bike in MINT condition has on it. BTW, it was only road one time for a triathlon in San Luis Obispo CA, in 1987....The same year it was bought (1987).

So here is my questions....the serial number says N6MXXXX. The x indicating the rest of the serial number I am leaving out. Why would the serial number indicate being manufactured in 1986 but then all the parts and color be that of a 1987?
More pictures to enjoy:

1987 Model.
Christmas selling season, with '86 mfg dates for sale as 1987 models.

This is a straight information thread. We appreciate the pictures, and they are appropriate for an OEM model. It's better posted on one or two of the other threads regarding Centurions/Ironman models, and since you came here for info to sell it, it's also suited for the Subforum C&V Valuation Inquiry thread....

FYI, there was no Master model in 1986, period.
Don't feel bad, a bike shop in Houston is selling an '86 on CL as a Master, too.
They know better, but are just trying to get the best price.

Please don't try to sell it here on BF C&V without paying the fee to do so.

Yours is really, really nice; it's a 54cm model the way Centurion measures it.

I recommend you leave your picture posts here, as well as the one with the OEM list of items, but change the date to 1987, then copy the same pictures and any questions you have here:

Vintage _ Cyclist, Amazing and Awesome! Great job.

R.T., not judging but that was some good sheriffing. Wait, maybe that is judging.
