Had several, crumpled like a coke cans, (don't think they were properly forged??) no warranties were upheld, standard dealer response- "rider abuse or You've been jumping with it." They would offer you a new frame at "cost". was the standard practice BITD, average frames, that sold well due to an expensive paint job was their sales gimick.
US built Gt's were far better frames, for a lot less Shekel, I have some that have been totally abused with no problems(Look what Hans Rey does with em!!!) Klein are just a rich mans(or foolish ones) a status symbol really. Handled nice, not a ride every day bike. Very light retail frames, but the race team frames were heavier
The press fit BB's were a backward step and real pain to change and get set up correctly, just another sales gimick.
I never understand the attraction in buying a short lived frame, when you could have a Titanium or top quality hand built Crmo one for less?
