This is my second BB on this particular MTB. When my LBS told me it needed to be replaced, it dawned on me that I was replacing the original BB. When I couldn't remember how old it was I decided that was proof enough that I should stay with the original!
I purchased a used bike with bottom bracket. I didn't feel it was smooth and also thought it was misaligned. I've successfully used a thread-together bb in the past so decided to do the same with this one. Although it has only been a couple of months, at this time I'm very happy.
