I'm almost done restoring an old Nishiki International. The bottom bracket was smooth before i took it apart. I used Finish Line bearing grease, and put a good amount in. After i tightened it up it seemed to have a roughness to it. If i let the spindle have some play it was smooth. Everything appeared to be in great shape during the cleaning. I know the retainers are in the right way as well...I suspect the retainers are the culprit tho. Should i just get new retainer bearings...or can i use loose bearings. And add a few to make up for the space of the retainer?
