Klein and Fat, much like brands like Seven and IF today, get a bad rap because they are expensive, and therefore those folks with loads of cash tend to buy them as their first 'real' bike...surely an expensive experiment and ultimately a mistake when they realize that they don't much like cycling after all! This happened alot (and still does...) and the result is that these expensive machines can be found hanging dusty and essentially unused in the garages of Doctors and Lawyers across the US, and all over the world it seems.
It's not Klein's fault.
It's not Fat's fault.
It wont be Seven's or IF's fault either. For some odd reason, rich fools buy expensive kit even when they know they'll never use it. Sub Zero refridgerators, Viking ranges, Porsches, Rolex Subs, etc. Same thing...
It's not Porsche's fault.
It's not Rolex's fault.
Klein, Rolex, et al...All these things are great products, somewhat tarnished in reputation by the image portrayed
for them by rich folks who have more money than brains and buy big becasue they think they need to and not because they have to.
Don't let the reputation of Klein as a pretty, under engineered, and overhyped product cloud your judgement. Kleins are exactly what they were designed to be, fast, light, well made, no nonsense race bikes from the heyday of the USA mountain bike industry. If you don't have one, you should get one, and stop trying to convince yourselves that you don't
need it.
