I just inherited a Gary Fisher Paragon Steel Frame Mountain bike. It has nice components but the only problem is the bottom bracket is toast. It has the press in style bearings/bracket. The bracket/bearing has backed itself out about a 1/4 inch. I think the bottom bracket housing has become slightly enlarged due to bottom bracket changes over the years. Does anyone have any suggestions on a fix. (i.e. oversize bearings, threading the bracket to accept a more common type bracket etc. I hope someone has run into this before and solved the issue.)Thanks
