so last week i was riding to home depot and when i arrived, it's about 1.3 mile trip, i noticed the chainstay had cracked right behind the bottom bracket. it is on a occ chopper. i had road probly 3 miles the day befor and can only assume it was already been broke by the way the brackes were acting. i realized when i would squeese the brakes it was pushing the chain stay out. crazy!!!
