No idea on the drive train efficiency properties, but finish line wax lube seems to keep the drive train cleaner than squirt. Anyhow, I bought a bottle of this absolute black and am going to try it. Installed it on my chain, waiting to dry now. Unfortunately, a lot of rain in the forecast so unlikely to take my tri bike out unless that changes. For right now I can confirm it makes your chain look dirty AF, which I can’t say endears me to the product given how much time I spent cleaning that chain before applying the lube.
Funny you should mention this. I’ve been using my own lube for a couple weeks now, and I noticed that it’s probably not nearly as good as hot melt at keeping the drivetrain clean.
For mine, this may be because I have a little bit of pure mineral oil in the mixture, fractionally <1% by volume, but maybe just enough to attract gunk. I don’t know what ingredients Squirt uses, but someone above mentioned the possibility of the use of “slack wax” which is essentially paraffin before it’s had all the natural oils removed. Those oils may be having the same effect. Just speculation, though, maybe Squirt is oil free.
I could try again without using the mineral oil. I just used it because most publicly available wax emulsion recipes include it.
But I may have to move on to figuring out how to get a wax-alcohol suspension. Or just give up and start fanning dollar bills at Silca.
