Just finished riding my last 3 miles of a 14 mile weekend warrior ride in Highland, Michigan on a 2007 Rush 3Z with a clean crack through the seat tube right above the weld to the bottom bracket. Has anyone else ever seen such a crazy crack? At least this bike has a robust design, as I was able to make it over gnarly rocks and roots with a busted frame for 3 miles. I hope Cannondale recognizes this as a defect and replaces. Does anyone else have this experience on their Canondale or similar single pivot frame?
