Bike chain lubes are mostly terrible, they are meant to work properly for maybe a few hundred miles assuming they were applied to a properly cleaned chain, properly applied and the weather cooperates. They all wear chains and chain rings quickly unless you are very good about cleaning and relubing your chain. 3in1 is still king unless you are racing. I would expect WD-40 to work fairly well because it cleans the chain and gets the filth out of the links, filth is a big part of drive train wear and we really don't need much in the way of lube as long as things are kept clean and rust free so the links move smoothly.

> I would expect WD-40 to work fairly well because it cleans the chain and gets the filth out of the links That it does, but it doesn't leave much lubricant behind, which you need for a properly functioning chain. As you know, you want something that will get between the pins and rollers and stay there, minus the grime that would turn it into grinding paste. Which is probably why some people swear by wax, but that sounds like a giant hassle.

  What I meant is that you can reapply WD-40 as needed, it may not lubricate the chain but it will clean it. Try that with PTFE. Wax is up there with PTFE for making grinding paste in my experience, especially on long, hot, wax softening rides.

That's not really true. There's lots of research out there showing that waxed chains result in less power loss over longer time compared to no lubrication and most other lubricants (both bicycle specific ones and more general ones). Now waxing your chain is admittedly annoying, but it does work.

  3in1 is actually bike specific, it fell out of favor with the rise of the modern bike lubes. Wax collects dust and dirt, especially when friction or the sun cause it to soften, which turns your waxed chain into a drive train eater and will cause power loss. More for the track than the road.

    Wax is great for road riding. I ride in Auckland where it’s wet half the time (all the time this summer). I re-wax every 400 or so km. It’s clean running and beautiful compared to the expensive oils I was using, and lasts longer. Wear appears to be down too. The reduction in grease and dirty chain makes is so nice.

      It is much better than the expensive oils, but not as good as old fashioned 3in1. The expensive chain lubes are mostly meant for racing, they give you the least friction by a long shot but don't last and most of them do not take well to reapplying without cleaning, you end up with grinding paste. Wax holds up quite well against water but does hold grit and tends to deposit it on chainrings, sprockets, and pulleys, and it wears them quicker than 3in1 will. Wax shares the downside of PTFE, you need to clean off the old before applying more or things start wearing fast, which is not an issue for everyone. It is nice and clean. Here in the winter of northern Minnesota, one good snowy ride with the road salt and sand will strip wax. Not that you would want to use wax in this sort of cold even if the road salt and sand were not an issue, wax gets stiff and brittle in the sorts of cold we get. I am an everyday rider and bike is my mode of transportation for everything, in this climate I need ease of reapplication or I will be replacing chainrings yearly.

        This sounds wild, and truely savage on gear. What sort of temperature are you getting down to? Any special gear needed for you or the bike? Here it’s never below about 5C and maxes at about 30C. It’s mild. The rain is the only thing that can be a lot. The most was about 250mm in a day, which is exceptional, but sudden, very downpours are common.
