BB is fine😂
I’ve never see a BB-CS20 before. I came out of my Schwinn Impact Pro easily which is a plus. It is not real crunchy but it does bind every couple of rotations in the hand. I removed the seals, dripped in some Liquid Wrench followed by 3-in-1 for no noticeable improvement. The sockets required for adjusting must come in the same set as those required to adjust PD-M324 pedals. Cool thing is that when I reinstalled the BB and put on the cranks, it spun A-OK.
