I was on a flat section after a long uphill, and I stopped to talk to another biker, then when I got back on bike and start pedaling, bam, the rear derailler just falls down, chain jams in it sideways and breaks too. I don't think I hit it on anything, and there was no damage to derailler itself. I was also in middle ring, so I don't think it is was cross chaining. My bike is stock with only 300 miles on it.




The derailler hanger piece looks very narrow to me compared to other bikes, probably so it would fit under the ABP.
Also, it doesn't look like there is a way to replace it on the trail even if you had a spare unless you have a big wrench with you for the ABP nut, which is screwed onto the hanger. The RD hanger is actually part of the ABP, it goes through the pivot, and the skewer goes through a hole in it.
Has anyone else had this happen to them, and was it covered under the 1 year warranty? If not, what was the price of the RD hanger, and also, does anyone have the exact procedure for replacing it?
I think I may need to get a spare one also and carry a big wrench around so I don't get stranded again, because I think the hanger piece is too narrow and this will happen again.
