Twice now I have had loose eccentric bottom bracket shell bolts. The first time I put blue Loctite on the bolts, but eventually I cleaned that off since it made the bolts so stiff that I could not tell how tight they were. This time I wrapped a couple rubber bands around them several times so that they can't unscrew themselves.
For reasons I do not understand, when I tried to post a photo I got an error message - "Cannot access attachments upload path!" I have posted photos before so something odd is happening.
