Interesting solution (?) for 'Itallian threaded bb comes loose'
Italian threaded BB's are know to come loose. I found a very interesting solution by a user in an other forum. What do you think?
This is alfeng's solution to the problem:
-'I' have chosen to put the FIXED cup on the non-driveside & the ADJUSTABLE cup which has a lockring on the driveside ... thus, avoiding the problem of the driveside cup precessing while I pedal ...[*]this was originally a "Why not?" solution which I decided to try many years ago when I-was-left-to-my-own-devices. ...
-Yes, 'I' have found that my solution works very well ...
-When the ADJUSTABLE CUP is on the driveside, the LOCKRING prevents the cup from unscrewing (i.e., precessing as you pedal) ...
Without the lockring (as when the FIXED CUP is on the driveside of an Italian or French threaded BB), there is nothing to prevent the cup from unthreading unless something like Loctite is added to the threads OR if the cup was torqued on with what I would describe as excessive force.
