I bought a 2007 prophet about a month ago. I was at the half way mark of a popular trail in Moab when the freehub locked up (bad pawls). This caused the chain to instantly double wrap the rear cassette. The derailuer broke in half and it snapped some teeth off of the cassette. My local dealer is talking like the one year parts warranty will only cover the hub. Even though the damage to the derailuer and the cassette were caused by the malfunctioning hub... does this sound right? What can I do?
