well ive got a slight problem, i checked that my bb was tight today and went to give it a little nip up , whilst tightening the drive side half of the part of the cup the tool sits in sheared off! im worried i might not be able to get the bb out if the rest shears off resulting in a ruined frame. has anyone else had a problem like this with a bb? also will it still be ok to ride on? i put lock tight on the threads when in put it in so im hoping it should be ok and wont come loose, its just i wont be able to get a new bb before sunday. thanks for any help pete
