|To lube or not to lube? That's a question
frequently asked of our tech expert, Tim Laflin.
In this edition of Tech Talk, Tim discusses whether you
should take advantage of those lube ports that Campagnolo
so conveniently provides on your hubs . . .
have gotten a lot of mail asking this question.
I have lube ports on my Campy Hubs and I want to grease
them. What should I use? Campy does not call for any
grease in the instructions.
Campy used to make a full line of lubricants. They have
quit doing this. The hub grease that they used to sell
was called Krysalis. It was a very light almost watery
Vaseline looking lube. It was light enough to inject and
have it flow to the bearings, but still allow the pawls
to clear it out. The thick lubes just gum up the springs
and pawls and it takes forever to clear out.
Campy`s current recommendation for the general public is
to not injection lube the hubs. The danger here is if you
use a thick viscous grease it interferes with the pawl
engagement and shortens the life of the hub and pawls. It
also causes increased drag from the hub. So why do we
chuck out all the cash on the grease ports? The real fact
of the mater is that a once a season rebuild is probably
all the hubs need and injecting grease is not needed. If
you are a competitive racer, and you don't mind the mess
the injection ports can be used with a heavy weight gear
oil to lube the bearings. It tends to get messy and need
to be done often. The excess lube will run out of the hub
to and down the spokes and all over the place. Once you
commit to injecting you are sort of stuck. It is a little
less drag friction wise, but a big drag for keeping you
and the bike clean.
For John Q Public, don't inject and just repack the
bearings once and season. If your favorite past time is
bike cleaning you can benefit from injection lubing.
