I already broke two frames. They were not top notch ones, both made in Taiwan, medium weight and not pricey, both replaced by warranty. First one broke after 16000 кms, second one lasted a bit more, I think it was about 17000 kms. I'm a pretty heavy rider, about 79-81 kilos(174-180 lbs) and like to push big gears.
Also I owned a frame that lasted about 20000 km then I sold it. I think it could be still alive but that frame was heavy, I think it was ~1900 grams for medium size.
