Hi RWI,

I've seen numerous posts about the ZF BB58 crown tube length. Starting a more definitive discussion... For people who would consider taking theirs to a watchmaster for shortening, does anyone know what the actual specs are for the gen tube? If you were doing this mod, what would your goal crown tube length be?

The recent ZF BB58 Blue I have on hand looks like it is just over 1mm. In either case, the ZF looks beautiful.
