yeah not broken, didn't think that was the issue, but if recall have to get it sorted out, probably won't break but you never know.
Yeah I really have no idea what the issue is/was, haven't had a chance to ride the yeti in anger (have to swap out the flat pedals...and maybe rebuild the fork), but the avids seem to work fine on it, jsut not on the xizang. Possibl the ti frame, or the new rims/pads... or a combo of all 3. But I'll just keep using the old XTs as they work pretty well
