I bought a new Trek 2200 one year ago, almost to the day. I was cranking up a hill, and the rear derailleur somehow caught up in the chain and it bent up and around and apparently into the frame, and I hit the pavement (just a little road rash, and got a ride home from a cute girl!). The end result is that the carbon seat stay is cracked, and the derailleur is mangled like Iíve never seen before. I'm not entirely sure how this happened, whether it was the Shimano part or the frame letting go causing a misalignment. The bike shop took photos and emailed them to Trek, and first reply is that this is not covered under warranty. Everything seemed to be running true prior to this, and derailleur was aligned. I was not shifting at the time. They want me to pay $800 to fix. I'll attach photos when I get them.
This seems unreasonable to me. I believe that this should be a warranty issue. Agree or disagree?
