The BB and the chainstay brace are different - They did not show up in the picture but the brace has small diamond shaped reinforcements at its ends exactly like my 85 Torpado. Another interesting thing is that it does not have a DR braze on. The area around the DR clamp seems smooth and round and I doubt that if a braze on had been removed it would be so regular.

I am comming to the conclusion that it is probably an early bike built either as an example, or before they had finalized exactly what they wanted the model to be.

A few other observsations:

The seat post measures exactly 56 cm but the bike seems considerably smaller than either my Ironman 56CM or the Torpado 56CM. It is also about 1 3/4 pounds lighter than Ironman and 3 lbs. lighter than the Torp. Somewhat unfair comparison though since those bikes have heavier stems and bars and grip shifters and different wheels.

I took it for a short ride and came to the conclusion that it is considerably more flexible than the Ironman or the Torpado. Is this typical? Seamed to me like the fork much more flexible than those of the other bikes.
