I seem to have bent the mounts of my rear derailler. They did straighten them out. I jump logs and stuff on the trails, crashed once but that was on the other side. Is this frame not made to do more then XC? I weigh a decent bit under 100 lbs but I do more challenging trails. Since I've been riding it, within a few months I've broke the rear disk brake, always knocked the gears out of wack like after most rides, bend the disks, broke the headset, bent the stays, etc. I'm now 1x8, is SS my next choice? I'm not sure if I can handle the hills with that. I do mostly rolling terrain though. Is this normal for so much repair on a not too old bike?
