Four strikes...YOU'RE OUT! I thought I'd share my horrible experience with Lightweight and their Urgestaldt frame. As I stated about, I gave up after 4 frames. The seat post slipped horribly on the first frame, the seat tube cracked on the second frame, the seat post slipped again on the third frame (even after me trying a thicker carbon past and gluing sand paper to the shim) and the bottom bracket was so out of spec on the fourth frame that the press in bottom bracket almost fell out! Instead of refunding my money (as requested), Lightweight sent ANOTHER frame (which I lost a lot of money on selling on eBay). I wish I had all the time, money and mileage back I've spent the last 3 years.
