i was out riding today thank god i wasnt pulling my trailer. i hit some big bumps and heard a big bang and when i looked back i seen my hitch for pulling my trailer bouncing down the road . pulled over right away and went to pick it up not beliving what just happen. luckly i was riding through the town were i work so i just droped it off there and went home to see just what happen. it looks like the small bolt on the bottom of the piece that bolts to the bike and then the hitch slids into this piece i must have over tightend it and it cracked the tube on both sides of hitch right were this bolt tightens the hitch down so there is no play when the hitch is bolted in place . if you have this hitch you will know what im talking about. just wanted to give a heads up to any one who has this hitch to take a good look at it before you pull your trailer the next time. not sure how i can fix to pull my trailer again kinda scared too right now anyway after this happend. any one wanna buy a trailer. ill try to post some pics tomorrow night of how it looks after it broke
