What lube is used? Why are they necessary?

These holes are for adding oil, not grease. Oil is used for time trials or other special events, and only when you are sure of good weather (no water) and limited distances. The hubs must then be repacked with grease for normal riding. If you shoot grease in the holes, then the entire annulus between the axle and hub body will be filled with grease, resulting in much more friction that a properly lubed hub. Campy hubs don't require frequent maintenance (every 5-10K miles depending on weather and dust levels), so any time savings by trying to use the holes for greasing is minimal.

Really? Why are they called grease ports then? You might try checking Campy's website for technical documentation
(i.e. http://www.campagnolo.com/pdf/178-rhub.pdf ) which distinctly states that the holes are for grease, not oil.
Sorry but Kerry's correctzelig1

Way back when and long before the internet, it was known that they were for oil as Kerry stated. If you can find a copy, now out of print, of the Italian Cycling Federation book on bicycling (CONI) which details biomechanics, training, diet, tactics and equipment, there is a long discourse about wheels/tires including specifics about oil which was used mostly in the context of track and TT events. This goes back to using shellac to attach your silk tubs to your track wheels.

Maybe they call them grease ports but again, Kerry's discourse on filling the cavity with grease is again correct.

2001 hub manual states that you should lubricate every 2500/3000 miles w/ grease injected through the greasing holes(hub bearings/hub body and free-hub bearings/freewheel body).Kerry is correct about the oil being used by specialists (TT), but that is not the reason for the greasing holes(according to campagnolo).

OK, make a mess (grease oozing out of the hub) and significantly increase hub friction. It's a poor way to lube your hubs.

It does, in fact, state in the official Campy manual that hubs equipped with "grease ports" (also freehubs with grease ports) should be injected with grease at recommended intervals. Thanks for the replies.
