Well at one point I had a stick come up in the fall and break rear cassette, chain, 3 spokes, rear derailer, they were all sram x5 I upgraded to x7's. I kept breaking a chain and come to find out my rear hanger was bent too. Then it was good for awhile. Since my bike fell off friends Jeep it broke all those components again so I just decided it was easy to SS less things to break. Well then of course I get new wheelset and it bends. My buddy is trying to take it up with them but doesn't seem to get anywhere right now. He did fix a bit so its ridable but who knows for how long.
