I have several C3 Ceramic lubes, plus the regular dry lube in my possesion. I use these on all my bikes. The chain stays cleaner along with the cassette gears. So glad I found this stuff. I have a full bottle of Rock & Roll, but I do not think it as good as this product. I am happy to find it available at several places, as it sometimes can be hard to find where it can be shipped to USA.
