This chain lube moved the 21st century closer to the 22nd century with drive trains that look like they just came out of the box. The well-known smoothness and quietness that Rock N Roll lubes are known all over the world for, just went to a new level 16 oz. It's not as thick as the Extreme and not as thin as the Absolute Dry. It's good for both mountain biking as well as high-performance road riding. The folks at Rock 'n' Roll say this one gives the best chain performance in terms of making your shifting faster. Gold lube makes a geared bike feel like a fixed-gear; the movement is that smooth. Like the Extreme, the Gold has a gel membrane suspended in the fluid. The membrane seeps deep into the rollers and stays there, keeping the metal parts flexing, moving smoothly, shifting crisply, and doing everything quietly.
