I have “multi-purpose” lithium grease from halfords. Can I use this on a Ti frame with alu BB cups?

Or do I have to use copper-slip to be sure of eliminating creakage? If so, this means I can’t go riding tomorrow until Halfords opens. Boo.

My maintenance regime is slack, so I’d rather do whatever protects me for longest.

Yes I have searched for other threads on the subject but they leave me none the wiser.

Copper slip normally there isn’t it.

For low maintenance I use park anti seize on the threads and good quality waterproof marine grease in your bearings.
