Over the years I've used several different chain lubes but this has been my favorite. I'm a big guy and live in a hilly area and generally get around 4000 miles on my Ultegra chains. I am pretty meticulous about chain cleanliness and lubrication. This doesn't pick up grit and dust and is easy to clean.
I initially used R&R but my LBS talked me into trying another brand. The other stuff gummed up and got dirty a lot more and my rear cassette started showing signs of rust. I went back to R&R recently and could tell a difference. Not as gummy and easier to clean.
I use Rock-NRoll Gold after almost every ride to clean and lube my chain and drive train. Very easy to use and eliminates my using degreaser to clean these components. Squeeze on the lube and just wipe the chain and chain rings and you're good to go. Absolutely silent chain. The only issue is it's a bit expensive even figuring on degreaser savings.
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.
I love Rock-N-Roll Lube as it doesn't turn black as a lot of lubes do when they break down. Easy to apply and stays on the chain for a long time (roughly 100-150 miles). I always buy two at a time just to have!
I've found this lube to be fine in the dry, but it does indeed wash off, quickly, when riding in wet conditions. It attracts almost zero dirt, so the chain stays clean. But in other-than-dry conditions-no way.
