I'd be concerned that this design might not fit tightly enough against the internal threads, possibly relying too much on lockring tension(?).
Seems like it might click or even loosen itself over time if there wasn't interference contact with the inside of the bb shell.
I have one of these Stronglight cartridges, and another branded Nadax, but haven't installed either one as of yet. At least the lockrings are steel.
