Does anybody know what kind of grease is in the sachet that normally come with a new chain? I've been scouring to no avail! I know that most greases are no good for rubber! as it soaks in a deforms rubber seals, o/x rings etc! Silicone and red rubber grease is no good for chain assembly but if I can find out the name of the white grease I'll buy a tube! thanks in advance for any help
