Help! Bottom Bracket Question.

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

You'll have to look at the seals on the bearing to see what size they are. Probably a four digit number.

Once you've got the old bearings and spindle out, you'll have to take some measurements to see how out of round the BB shell is.

Loctite offers a retaining compound that might work: https://www.loctite.com/cps/rde/xchg/...UID=0000000HWO
