Isnt the whole wax-on-chain thing just a recipe for disaster when it comes to sand? I mean, doesnt the wax just attract more dirt and debris, which in turn accelerates wear on the chain? And what about the whole hydrophobic argument - doesnt that just mean the wax will repel water, but not necessarily protect the chain from the abrasive effects of sand? And how does the wax actually prevent corrosion when the chain is exposed to salt and moisture, which is often the case when riding in sandy conditions? Is it just a matter of the wax creating a physical barrier, or is there some other mechanism at play? And what about the trade-off between waxs protective properties and its potential to compromise the chains lubrication? Ive heard some people say that wax can actually increase friction on the chain, which seems counterintuitive if the goal is to reduce wear. Can someone explain to me how wax is supposed to protect my chain from damage caused by sand, and what the underlying mechanics are?
