Yes, it is formulated for use across both road and mountain bike shifting systems. As long as the interface involves steel-on-plastic or steel-on-composite, this grease is the correct choice.

You should consider re-greasing if your shifting feels heavy, sluggish, or inconsistent, or if you are performing a routine cable replacement. If you notice the original grease has dried out or become contaminated with debris, it is time for a refresh.
