your an idiot. for one thing, the cup broke when it was still 2mm from the frame, under a normal amount of torque. the lbs gladly exchanged it for one that fit properly. second, i've bought and installed plenty of bb's and i have never had one come with installation instructions. luckily, replacing a bb rates just above inflating a tire on the scale of technical difficulty. if you think knowing how to install a bb makes you a master mechanic then I'm sure you also have trouble finding a helmet large enough to fit your big head.
