Using the chain after apply Silca hot melt wax for a month now with a 600 km ride. Love the cleanness of the chain (see the picture of my bike that never clean up the chain for a month) because there is no need to apply any lube on it. The chain is so quiet. Appear to be cheaper than using the loop as I don't have to apply it often. I have done the wax on 3 chains and there is still plenty of wax left that I think I could do it for 5 times at least.
To be blunt, I’m **** about bike maintenance, and can’t stand a dirty drivetrain. The Secret Chain Blend was the answer. Even after about 200 miles the chain still looks like I just put it on. Plus it’s super quiet and while I can’t speak to any shifting improvements(I replaced the cassette and chainrings at the same time), or longevity yet, Secret Chain Blend is a winner in my book.
