• You interpreted that correctly, unless the plan is to rebuild them with new grease after every wash, in which case have at it.

  • Ah, I interpreted that as persistent jet washing will kill any bearings. They do claim to use labyrinth seals, but perhaps they're of a lower quality than the CX75s.

  • CX75 and RS505 both use Contact hub seals.

    SLX FH-M7000 weighs about the same as RS505, but has Labyrinth & Contact seals. The flanges are further apart and you'd have to use an MTB cassette if you want 11speed.
