Mostly stuff that is only the high price it is/was because of the stickers - and that's most expensive stuff IMO/E.
The most disappointing bike I had was one of those box section Paces - always loved the looks. Bought one in the beautiful anodised red. Rode like a brick. Sold it in weeks.
Only ridden a couple of 'Dales - again nasty riding bikes - dead feel. (And this is not an anti-alu bias!)
Over-priced nostalgic steel in general. Especially the "made by Americans so must be better than those Taiwanese can do" (or even than a British craftsman can do) - a sort of racism really!
And Kleins - just about ANY bike can look as good with the right paint job!
I'll get me coat...
