There are so many different lubes to choose from that it can be overwhelming. And, it seems like one is as good as the other. But, lab testing has shown as far as drip lubes go, Rock-N-Roll Gold reduces friction and wear more than most other lubes. It's easy to apply and does fairly well at repelling dirt and grime. As far as lubes go, Rock-N-Roll Gold is a great choice.
This lube is fantastic. No gooey mess and build up on my chain and I have not heard those annoying squeaks that often happen. I have been riding and working on bikes for decades, including time in bike shops and this is the best lube yet.
Rock n Roll Gold does an excellent job removing road grime from your chain while also lubricating it. However, it breaks down easily, especially in wet conditions. It's also less viscous than a lot of other lubes, so I have some trouble controlling the dose (i.e., it's harder to drip link-by-link without spilling excess). Fumes are really strong, too, only apply outdoors or in a very well ventilated space.
I've used this Gold Lube on my 'gravel bike', in a variety of weather conditions, dry, drywet, and wet. In the dry, this lube works quite well, with a nearly-silent chain, and fast shifts. In the wet, I found that this lube washes out rather quickly, and the chain becomes noisy. I experienced 'chain-suck' several times, although these chains were win spec, via a chain-checking tool. So, this lube is quite fine for the dry, but if you have wet conditions, look elsewhere.
I ride a trike, so my chain is very close to the ground. It's down where the dirt & water can do it's damage. Rock N Roll Gold keeps my chain working like it's suppose to. It's easy to apply & stays on well. I can't imagine using anything else.
