Odd. Fulcrum with that preload ring tend to have cartridge bearings, and they disassemble easily enough (usually: use cone spanners on lock nuts, remove preload nut, remove cone/nut with a bearing seat, whack the axle out with a mallet). Keep the old bearings and use them to press in the new bearings, just don’t forget to reinsert axle if it’s a stepped axle fitted between the bearings.
Leshaches-
Yeah, they're cartridge.
I was on the roadside so only tried fully undoing the lockring, didn't note any spanner flats, I'll have a look when we unpack the carnage.
I'll only replace the bearings if I already have the spares for it. If not, I'm sending the missus down to the LBS with it.

I can't see anything out of place.
The NDS axle looks to have a lip on it to stop it moving right through the bearings but I can't see how the lockring thing comes off (other than by force).
Oh maybe the NDS side is an axle cap and just pops off. The might explain the lip.

Something up with the grrl's front wheel. Bearings gone maybe?
Basically the bearing pre-load thinge (ring that tightens down on the bearings and is then locked with an allen key), well, when it's set to remove side-to -side play and the wheel spins ok... as soon as there's load on the wheel it squeals and then stops.
I had to back the lockring way off in order for the wheel to spin freely, to the point there was quite a large amount of side to side play and the braking was noisy. Not a great start to a 400k in Wessex.
I can't even remember what wheels they are - "Fulcrum", she reminds me. I'll be able to get some pics of the mess later but anyone seen this kind of thing wanna have a stab at the issue?
Also, how to pull apart cheap Fulcrums to swap bearings? I may have spare bearings for these but I'll need to see how to pull them apart.
