Im a former Cat.1 turned daily commuter on mixed terrain and this is by far the best lube Ive ever used. After a wetmuddy ride you simply have to wipe your drivetrain off. Follow the instructions and this wont disappoint.
The hype around the Ceramic line from Muc-off put me off at first. It just seemed to good to be true. I've been using C3 for about a year now, and its as good as advertised. First, it really does keep you chain cleaner. Not at all sure how that works, but dirt just doesn't seem to accumulate the same as conventional lubes. Second, it is so quite. After I've done a thorough chain cleaning, I can hear the chain click-clack as it goes through the gears. Lubing it with C3 and the sound almost disappears--its amazing. But the real proof is in its smoothness. It is literally noticeable as soon as the chain is lubed--it spins noticeably faster and smoother. True, this stuff is expensive. But if drive train operation is your holy grail, C3 is fantastic. I use Dry in the summer, but really prefer Wet at least 75% of the time.
This is definitely the worst lube I've ever used, except for the Dry version of the Muc-Off C3, which is just as bad. Maybe it lubricates while it is first applied and still wet, but it rapidly forms a black, abrasive, sticky paste that is nearly impossible to get off a drivetrain. You don't need to be a tribologist to know that a thick gritty paste is not going to effectively lubricate moving parts. It took multiple soakings of automotive brake cleaner to get this gunk off of my drivetrain, bike degreaser could not cut through the paste. I'd suspect corn oil from the grocery store would work better as a chain lubricant.
