Whilst everything above is essentially true, personally I think there’s a bit more too it
For me its re-connecting with the amazing mtb social phenomenon that happened in the UK in the late eighties, early nineties.
mtb boomed in the UK almost from a standing start in such a short space of time - it really was a golden era
A heady mix of innovation, marketing, fashion, colour, newspaper headlines, you name it
MTBs then were cool in a way they just aren’t now
For me it’s these feelings which ensure an enduring appreciation of this era of bikes over and above both older and more modern machines
