Is it worth trying to lube a speedo cable?  With what?
My problem is noise when cold (below freezing) that fades
when everything warms up--after maybe 25+ miles.  Cable,
not the speedo gears.

I remember "in the old days" when one used graphite
powder, but the newer plasticized cables seem to be
spec-ed as not needing lube.  Advice based on
experience?

Thanks,
Richard
