Fulcrum zero free hub
At some point yesterday the lovely clicking sound the free hub on my fulcrum zeros used to make disappeared. So the bike is now completely silent when rolling, which is disconcerting. Does anyone know what's happened and whether I should worry about it (ie Hub about to explode, etc, etc)?

Pawls can stick down if your freehub has got gummed up. It's a straightforward procedure to take off the freehub, clean and lubricate the pawls and re-adjust the bearings if you are familiar with maintaining cup and cone hubs. But as long as your freehub is still freewheeling and takes up the drive OK when you start pedalling, I don't think the lack of noise is anything to worry about. It may be the grease put in at the factory has moved around a bit in the freehub with use and has quietened down the clicks.
It's touching that you've overestimated my mechanical prowess ;-)
Is there a very simple, duffers guide somewhere that someone knows? I'll give it a go...
However, best to check the technical manuals on the fulcrum website. Failing that, see if there is some video on youtube.
Once you find out which tools you need, It's really very easy
So the issue with my hubs is that the small stell cable that holds the three little legs up (pawls?) has snapped. This meant that one of the legs wasn't being pulled up to engage and I guess was diluting the clicking free hub noise. It now also means that as I've taken the cable off the wheel now has no engagement, which I guess could have easily happened out on a ride?
So guess I need a new cable thing from fulcrum/campy?
You are guessing correctly. Give a ring to the Cycle clinic tomorrow, I'm sure he can sort you out something
It's called pawls retainer ring and it's an open ring
Edit: Just had another thought. Are you certain that ring has snapped? It's not a closed circle. It's an open ring that you spring open to fit and then it springs into place.
Just thought I better check, having ordered those rings and pawls previously myself only to find I didn't need them after all! My problem was that my old alloy Record freehub had cracked along one of the splines. The later design is beefed up. You should find it easy to replace the ring and re-assemble. Those Campag/Fulcrum hubs are simple for home mechanics. You don't even need cone spanners.
