No clue. Lower volume production run in '85, as the Comp TA was rebadged.

The expensive productions of the '83-'84 Turbo, '85 Cinelli-made Equipe and high-end Prestige, which didn't sell all that many units, tended to keep Centurion conservative.

'86's Ironman saw two things happen: increased sales, especially of the red/white, and even higher units sold of the Elite, which was cheaper and Tange 2. This continued with the '87 model year, probably the most Ironman bikes sold that year, but were outpaced by the Lemans and Lemans RS at $200-$300 cheaper.

'88 and '89 saw more sold than '86, I'd bet, with the tricolor group and Dave Scott continuing his success on Wide World of Sports. At the same time, the Lemans and Lemans RS continued to roll out of shops when buyers couldn't pay the Ironman price.

I got this info a little while ago from a bike shop that sold Centurions. They didn't discount Centurions one cent, but sold a ton because the other brands didn't have the component levels for the price. The shop owner also told me that when the '87's came out with the Expert and the 105 group, the local tri-guys showed up with the cash. He said he sold Experts 4-1 over Masters until '88 and '89, and then it was more like 2-1.

Most people don't remember, but $50 and a group difference could make or break a bike's success back then.
