0_0 I just remembered what i THINK caused the fail in the frame... 2 months ago, my friends goped was broken, so i let him sit on the rear rack (which i installed). The rack was mounted to the two tubes that come up from the rear axle area. We would go everywhere, over all types of ground. We did this a few times. After that is when i noticed the crack. Please dont give me grief over how dangerous it was. I know how dangerous it was which is why we stopped.
