So before I go on the big trip, what bearings should I consider replacing? (im pretty mush asking what bearings will last 7000km/4400mi)

Jockey Wheels: Shimano XT RD-T8000 rear derailleur
Bottom Bracket: Shimano BB-MT800, unknown bearing type
Front Hub: SON28 disc brake front hub, cartridge bearings
Rear Hub: Shimano XT M756A rear hub, cup and cone bearings
Pedals: Nukeproof Horizon Pro Flat Pedals, bushings & cartridge bearings
Headset: FSA Orbit MX headset, cartridge bearings
No one will be able to tell you exactly how long they last, because people ride in wildly varying conditions. Like [MENTION=21724]cyccommute[/MENTION], I'm convinced enough by the longevity of cartridge bearings that I would trust anything that still spins well on tour.
