I favor Phil Wood or Park grease. But all greases lose the volatile components over the years. The Campagnolo grease is pitiful stuff. What were they thinking? I can only think that race mechanics changed the stuff by the week.

So that leads to another Campy error they never corrected (admitting mistakes is not an Italian thing). Basically using a 1/8" or 3/32" round (chainsaw) file you can file the devil out of those cracks at the spider joint. Just make sure you get to the root and nicely profile. I would guess that a crack of 3/32" would be too deep, but the risk is yours.
