i'm reading the question as brands that were (supposedly opinion) cool back the day, is that company still cool today, in its current guise? (as opposed to cool back in the day, do I still think they were cool)
Its a pretty sad state of affairs really. There are lots of companies making great stuff, but not necessarily cool (IMO). But most of the cool companies from back in the day, are either gone, or just, so far from cool...ugh.
But there are some...
Yeti, I personally don't love their direction, but they are obviously doing a good job of catering to their market (just not me any more)
Santa Cruz, there was a time I wouldnt be seen dead on a Santa Cruz, but these days I would, basically the opposite of Yeti.
Intense, still doing a good job.
Moots, always lovely stuff.
Ritchey, nice parts and cool frames, not quite the level of the old days, still cool though, only reason I didn't buy a new Ultra is...
Fat Chance...must be still cool, I just bought a new one.
Litespeed...I think they went through some troubled times, but seem to have come out OK.
Selle Italia, Flites were cool then, SLR's are cool now (well to me)
Also Chris King and Cane Creek, while i never thought of them as "cool" back in the day, like ringle/nuke proof, just great solid products...they still do the same thing today.
