I’m having a bit of a Fulcrum wheelset nightmare myself with two rear wheels needing an overhaul at the same time.
I think the bearings for your hub are the same as on my Red Metal 1 XL hub (RMO-008), which is translates to 6804, and is available from any decent bearing supplier. You may be able to save a bit there.
I’m less sure about the bearings required for my freehub (same as yours). I’m waiting for a pair of circlip pliers before I can get at the inner bearing. Apparently the bearing is a pig to get out and worse to put the new one in.
I stumbled across the i-ride site too. It’s the UK site I can find stocking a range of Fulcrum spares. Together with the non-existent customer support from Fulcrum, I’ll be retiring these wheels if I can’t sort out the freehub bearings.
