Which do I grease??(4 posts)

Which do I grease??JBurton

Which cables require grease, which don't and how do I tell the difference by the looks of the cables? I know that some could be damaged by grease, correct?

What are the preferences: Grease or lube? What brand/kind?

I don't know that you can damage a cable with grease- maybe a gore-tex, teflon or otherwise fancy cable can't take it, but I wouldn't recommend any of those anyways.

All cables should be greased (very) lightly, what kind of grease isn't really important, but I lean towards a lighter formula like Phil's for applications like this.

Well, most housing these days is lined, either with teflon or something similar. When you look at the end of this stuff, there's a plastic tube inside the metal spiral or rods, depending.
Lined housing and grease don't mix well, not because of chemical interaction, but space considerations. Older, unlined housing had slightly more room inside, as it was designed to hold a layer of grease to reduce friction.
The lined housing works well with a light oil - I like to put a few drops in the housing before running the cable through, and wipe the exposed cable afterwards, to remove excess. However, Shimano does supply their Dura-Ace housing with a grease pre-installed, which is working nicely, but it's a very light, thin grease.
That Shimano Grease is just awsome on cables....MrCrud
