I recently purchased a 90 team fat on ebay and found the bottom bracket spindle and bearings bound so tight I cannot get it out with a two pound sledge hitting a maple board and then the spindle. I have two other fats from 1989 and I know the bottom brackets get tight, but I was always able to get them out. The seatpost is in like state. I have practically soaked these in penetrating oil to no avail. Short of using heat does anybody have any ideas on how to free these items from the frame?
