It s Neco, if you need changing it.
Don t worrry about your BB unthreading,
plenty of grease,
and make it tight tight.
Check it after the first rides,
retighten.
If the worst should happen ,
you will feel some play before it comes off.It won't explode suddenly.
I could not find Skant's thread mentioned the German bb. Do you have a link please?
