Just checked the Trunnion bearings. The seem to be plain black with no markings which suggests they might be ABEC3 Enduro. Hard to tell though.
However they are still as smooth as silk.
One thing I have noted is that the trunnion bearings needed (F6900?) seem to be pretty rare (at least online) on this side of the pond so I have set of those on their way after managing to find some. I couldn’t locate F6900 LLU bearings but I could get 2RS, which should be well sealed enough according my mech eng training from the distant past. The other bearing have the tell tale red seals of enduro llu bearings.
