i know quite a few that have snapped or welds cracked etc... something you dont expect of a 2k frame... but as to your question i dunno how i snapped it. i noticed after a ride home from work there was a massive crack but i honestly dont think it was that

but my tazer on the other hand, that was riding home from work, hopped up a 2ft wall and as i went to manual off and the frame was toching rubber. got off and checked over very quick. my concerns were the shock but couldnt see nothin wrong so carried on riding (i ragged it home too, god knows how i didnt hurt myself) got home had some dinner then decided id find out what i broke. then i noticed a big crack around tthe top swing arm so took cables out and the rear end just fell out. i literally rode home with my gear cable and brake hose keeping my back end together
