Somewhat interesting update on paraffin wax for bikes:
I've been waxing my bike chains for years. Many, by now.
Last year, i started using the fanciest paraffin wax i could source, from a professional seller. Very low oil content, i think pretty much lab grade, whatever that really means. I have now ridden thousands of km with the stuff.
I get virtually no wax residue in the cassette, chainrings, pulleys.
In the past, with wax pellets i bought on amazon / supermarkets that were marketed as multi purpose paraffin wax (i assume mostly bought to make candles), i had instances where i had to remove wax residue between cogs, because it was causing mis-shifts. And the pulleys needed degunking regularly (mostly big flakes rather than outright gunk). It wasnt bad, i assumed it was normal, because it's wax after all.
But i've realized that this is entirely gone.
Now, does that mean my chain / drivetrain last longer? No idea. I have to test chain wear (i'm only on chain #2 on my LT268), but it's not like i'm on chain #6, and as a chain lasts for thousands of km, i really dont keep track over time of how long chains last in any scientific way.
But i thought i'd share here that paraffin waxes DO differ. Without additives, whether that makes a difference to lifespan, idk. But my drivetrain is always clean AF, it's really just black dust / incredibly thin black flakes that come off my drivetrain. It's so, so nice not to deal with oily and gunky drivetrains. My rotors are now way nastier than my drivetrain, funny enough. Because if i rub my rotor with my calf, i get a black mark. W the chain, virtually nothing.
