I’ve never seriously considered waxing a chain before. It just seems like a massive, messy, PITA to get a small potential gain. But the method described by Silca seems much lower effort, and lower risk in the mess department. Also, much since it works in the ultrasonic cleaner, there’s no chance I’m going to ruin anything that wasn’t bike specific in the first place.
More interestingly, is that the sous vide method described in the video shouldn’t be limited to their $40/bag “Secret Chain Blend” wax. I can’t see why it wouldn’t work with any wax, which dramatically lowers the financial barrier to entry.
