I bought a new BB, which is well recommended, installed it. After going out for a ride it sounded a little clicked, so stripped down the BB, and one cup was properly stuck - not cross threaded, just needed a huge amount of torque to remove.
Looks like threadlock on the threads out of the factory....
I've always greased up the BB threads before installing, as threadlock seems unnecessary, as the crank arms will stop the cups from unscrewing.
Anyone heard of threadlock on BBs? Should I be unimpressed? (obviously I should have been paying more attention to what was on the threads.) I must have been half asleep when installing, as I always grease the BB threads.
