I agree with Dr S - if it's pre-90 it needs to be really, really 80s
In a normal month I'd go Cunningham, but it's so ahead of its time that it doesn't really represent the 80s somehow.
I think there is more to it than that. Even in 1988 it was still so advanced, but that for me is the rub. If Bushpig had presented that bike but said it was from 1981 or 1982 then it would be beyond a doubt a clear winner for me. It is afterall the ultimate grail bike for me personally and i would do anything to own it. The innovation and craftsmanship is astounding and to me it is the highest form of bicycle art. But because it is a late example, in my heart I feel that it loses some of the mystique- its like a late Jag E-Type V12. Probably a much better car than the spindly early series one E-Type, but somehow does not have the same charm.
In a regular BoTM it would walk it, probably even take BoTY, but for me, being a special month, it needs to be a bike that would not stand a chance in a straight fight, something that your regular RetroBike member (who understandably prefers the 90's bikes that they grew up with) would not normally go for.
I have narrowed my choice down to a few bikes that fit that criteria, but i'm really struggling to pick 'the one'.
