Hmph? (scratches head) Go figure.
"Labyrinth seals are non contacting rotating labyrinths through which splash water
cannot enter and gravity drains them. Sturmey Archer hubs are classic examples
of such seals. They are more than 40 years old and used in the rain, yet the hubs
are clean and dry inside with no wear or frictional drag....It has the best labyrinth
non-contacting seals of any hub." Jobst Brandt
