Far too much to spend on a bike whether it is brand new or cult-status. Saying that, I’d happily build that Klein up and go ride it…suspect it’d ride very well.
This idea of ‘old-style’ bikes not riding well – utter mince – back then, they were the latest thing and rode very well…if people are only used to riding sofa-comfort big travel bikes then everything that doesn’t have that kind of travel both ends will apparently ride terribly. Things move on and geometry changes, but if you can ride a bike…you can ride any bike, it just comes down to your ability as to how well you can ride it.
Nowt wrong with that Klein apart from the price.
P.S. I’m a million miles away from riding well let alone a riding god…so my opinion isn’t based on me thinking I’m better than everyone else, actually the complete opposite, but I do believe it is rider ability that makes a bike ride well and not the need for umpteen inches of travel.
