not really my fault or a riding thing but I got rear ended with two bikes on the back of my car.
The Tora fork pushed a big dent into the back of my car but was undamaged. Front wheel and cranks were toast through.
Otherwise I did this to my Giant Warp. I had this bike during my Townhilling phase and hucked it to flat concrete far too often. I can't believe it held up as long as it did.
