May have been built in 1987, but model year is 1988. Centurion produced the Dave Scott Ironman Carbon and the Carbon, both for 1988 only. "Squiggle" graphics were also 1988 only. The Ironman Carbon was OEM Dura Ace, 7400 series, 2x7 DT shifted. The Carbon model was 6400 series, 2x7 DT shifted. The seatpost size was 25.4, and the cockpit was Nitto stem/B115 bars. Fast and flexible. That frame size probably is a bit stiffer. Beautiful bike.
