I recently got annoyed by the propensity for my jockey wheels to
run out of lube. The trouble I suspect is that it is difficult to
adequately lubricate them during assembly, so I made it possible to
lubricate them after they are assembled.

I bought a grease syringe that fits my grease gun, and I drilled a
hole into the jockey wheel such that I can pump grease directly
into the middle of the plain bearings.

Campagnolo jockey wheels use a soft metal outer bearing material,
so it was easy to drill through the plastic wheel and the bearing
material.


You mean the Campagnolo jockey wheels with the plain bearings (10
sp)? Get rid of them and buy Tacx jockey wheels with stainless steel
ball bearings:

and you are done especially in your Australian climate. Campagnolo
stuff is very durable except their jockey wheels with plain bearings.
They are crap.


Thanks for the suggestion, but the standard jockey wheels seem to last
quite well for me, provided I can get a good dose of lubricant in to
them - which is now very easy for me.

I tried some jockey wheels with sealed bearings many years ago. They
were made from aluminium and wore out relatively quickly, while not
noticeably making a difference to gear changes. Maybe the Tacx plastic
ones are better these days, and maybe when I wear out the stock jockey
wheels I'll try some.
