GOLD is for both mountain and road bikes. A universal dry lube suitable dry dust and protection from slightly wet conditions.
This chain lube moved the 21st. century closer to the 22nd. Drive-trains look like they just came out of the box. The well known smoothness and quietness that Rock N Roll lubes are known all around the world for. Works well for on and off road, so if you do both, or want a superior lube for either, this is the one.
