There are so many chain lubes on the market that it comes down to your personal preference and budget when you buy a can of it. The key is to remember that a little goes a long way. Don't just saturate your chain so lube flies off and gets all over your bike and gear when you ride. Instead, lube it after you return from a ride so that the chain and O-rings are warm, allowing them to absorb the lube better. Over the years, I seem to be drawn to Maxima Chain Wax and it has served its purpose well for my fleet of bikes. As a general rule, chain wax is more water resistant so it tends to be good for ADV, dual-sport, and dirt bikes, while chain lube is more for streetbikes. But wax builds up quicker and requires my dutiful maintenance.
