I got a new bottom bracket; bsa30 or whatever for Race Face Cinch cranks, if it matters.
Last week looking for a creak on my bike, I discovered the drive side bb cup was ever so slightly loose.
Took it off, cleaned, greased and put it back on. Gave her an extra uggadugga, as @roflbox would recommend.
Nope, the drive side cup came loose again tonight. I thought it was the preload thing on the cranks, but noticed that the ISCG tabs that are splined behind the cup are also loose. The thing got so tight while I was trying to nurse it out of the forest that I had to start walking.
This is the first time a BB has ever come loose on me. What would cause that? Am I just not giving it enough beans tightening it? It seemed plenty tight to me. And while pedaling, aren't you spinning the bearing in the tightening direction anyways??
