Comp TA 56cm - I bought from original owner. It matches up with above specs, except for rear derailleur, tri color. Bar tape is OEM as well. Shown with new tires which I put on.

Back in the 80's, I managed the first triathlon store in the US in Berkeley California, called, naturally, The First Tri. We never called Mr. Scott by his name. He was simply referred to as "The Man".

The store only lasted a few years. Had we been a Centurion dealer, perhaps it would have lasted longer. Seemed like every runner or swimmer that decided to do a triathlon went out and bought one of those "The Man" bikes.

I've never seen a Purple Haze with those type of Tange decals.

I have seen these:

Quick trip to the garage, you are correct. I remembered wrong on the decals!
Seatpost is definitely a non-fluted Sugino and is 27.0 (27.2 won't fit). Perhaps the bike shop I got it from did a switch.

Great summary. I am looking forward to completion of the photo record and I think it would be great to have a picture and description of the first Diamondback following the demise of the Centurion brand to serve as a bookend to the saga. Wasn't that Diamondback basically a rebadged Ironman?

I took the liberty of transcribing the above into a spreadsheet on google:

https://docs.google.com/spreadsheets...gid=1927924249

I'm sure there are errors. What I'd like to do is open this up to editing control by "the brain trust" to be determined. I never did one of these online spreadsheets before, so I have to figure out the sharing function. I think I'll need emails to send editing invites.

Review and Comment before I proceed.

I think this document could be used to wrangle together a lot of info in one place, including images (already started, see year tabs on bottom of sheet).

Additional info like known touch-up paint options struck me as one thing that would be helpful. I keep seeing that issue raised in the forum.

You are correct on : non - fluted Sugino seat post 27.0. All the 88 masters came that way. Even stock pic of Dave Scott hoisting one shows that.
Sidenote: Before I forget the 86 classic suggested price was 525.00, however my LBS had it at 575.00. Also, short cage definite on 86 classic as it was the only shimano 600 sis rd available in 86. Thanks.

After looking at the spreadsheet on the other page, the BB on my ironman was a Sugino, not Shimano weirdly. It has a thick lockring, just like the Thick one on the Superbe Pro BB, and the cup is clearly marked Sugino.

Seems everyone is wondering why didn't they just put matching shimano bottom bracket. According to a bicycle review it was simply to keep build cost down.

My '87 master is, to the best of my knowledge, all original...except of course for the tape, tires, pedals, and housing. So, in case it helps filling out the spreadsheet, here are pics of the crank, derailleurs, seat post, and headset:

Mostly original '89

http://s6.postimg.org/gbxwsjyxp/20150708_170549.jpg

As far as the supposed geometry changes, would it theoretically be possible to just measure two vintages of frames in the same size and compare? Especially since we have one of the spec sheets above. What does it take to measure frame angles other than a protractor?

I have a 1989 Expert and a 1987 Expert in the same size frames, and i measured them rather crudely one day and they are different geometries. IIRC, The 1989 had a less relaxed head tube angle as the 1987 had. i recall it was a couple degrees steeper. When i find the sheet that i noted these items i will post them here so others can get the idea.

Database update https://docs.google.com/spreadsheets...gid=1927924249

I added a general groupset note for each model to indicate group (600EX, 600 Ultegra, etc.) and miscellaneous stuff like anodizing.

If anyone who has bikes original (or known provenance) to them, with original parts, they can let me know specific part numbers (i.e., 6200 series vs 6208 specifically) for that year and model, which will enable me to put the specific parts in.

Geometry charts added for 84, 86, 87 and 89 models.

If anyone has any other ideas on what would be good to include, let me know.

Re: series 6200 parts for 1984 through 1987.

On the other Ironman thread, lord_athlon confirms his original 87 Master is all 6208. (although I'd like a recount; I suspect the crank, FD, pedals and headset are 6207, based on Shimano's products from that year).

Since 6208 was issued in 1986, I assume in 1984 and 1985 the Shimano components on the Comp TA and Ironman would have been all 6207.

In 1986 Shimano introduced 6208, but the 600EX group sold was a mix of 6207 and 6208:
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]
  • [*]

1986 had SIS and aero brake levers, which would eliminate the italicized parts in the list. As already noted, brake levers would have been either Dia Compe or Shimano, both aero. This is assuming the 1986 Ironman did not come with leftover components from Shimano's 1985 lineup.

Robbie...this is a great thread...and great idea on it being simply informational...We could probably use an entire encyclopedia of threads like this...

RobbieTunes 10-21-15 01:25 PM

Keep the corrections coming. Looking for documentation of a 1988 Master in yellow/white "straight fade."
