Can anyone tell me what bearings are in these, are they custom or a standard 6800 series?
they are custom though Enduro bearings fit and you can still run the hope 'labarynth' plastic washer thing
61805 i think but you've got to make sure you get the 24mm internal diameter ,probably best getting proper hope ones.
When you get the Hope brgs take the seal from both sides the brg and get some really good water proof grease and get as much as you can into one side and refit seal, then do the same to opposing side (get as much grease in there as you can and refit seal. To finish remove seal on 1st side you started and regrease and it should last at least 3 times longer.
When they come from brg factory they have hardly any grs in them. Good luck. 😆
