I always think of Kleins as the Cheryl Cole of mountain bikes. Cheryl Tweedie is the Cannondale of mountainbikes. Both are the same but one got a better makeover and is therefore considered more desireable, whereas your common 'Dale will give you the same kicks but up behind the wall behind the chippie for the price of a few doubles down the pub.
Like Cheryl, Kleins look fantastic, with a healthy shine, but you wouldn't really want to live with one on a day to day basis, due to the fact it will leave your battered wrists weak, limp and lifeless. She/ they probably don't ride as well as you would imagine too i suspect.
Finally, just like Cheryls marriage, cracks soon appear followed by complete and sudden failure.
I have yet to see a Klein doing terrible shampoo adverts in a terrible regional accent though so the above could be complete bollocks.
My advice would be to continue knocking one out when you see one rather than getting personally involved. Its only going to be expensive and a dissapointment that will end in tears.
