Cable lube

Ummm -- never seen one of those before. How does it work ?
It clamps around the end of the sleeve and onto the cable. It has a hole to put the stem from the spray can into, so when you spray it forces the lube down the cable.

Thinking about it now, you still have to get one end of the cable free to clamp onto, but it does make getting lube down there much easier.
 
tbh Teflon lined cables don't NEED lubing. But the nipples benefit (even if they have plastic sleeves).
BUT I have seen plain galvanized cables rust esp where they exit the outer ferules - I put a bit of ACF-50 PURELY as a rust inhibitor. It creeps everywhere via capillary action - takes months to stop traveling. A bit on the nipples smoothed action on new cables - They are stainless wire so don't rust - but friction is friction.
