I had a chance to hang out with Mike Kaelon, who handles Rockshox Service, as well as Quality Control and Research/Development for KHS Bicycles. We got to talking about chain lube. Check out what he had to say…
BC: Which type of lube is best for chains?
Mike:As long as they are used regularly, most lubes work great. The only exceptions that I’ve seen are wax-based lubes, like White Lightning. Those will work OK, but you really have to work at keeping the wax from building up on the outside of the chain, which can prevent any new lube from getting inside the links. If you use wax lubes like most people do, which is to just apply the lube and forget it (which is why most people use those lubes, because it doesn’t get dirty), the wax starts to build up, and eventually all you end up doing is putting new lube on top of the old build up, instead of getting it worked down inside the links.
BC:Is there a brand you prefer?
Mike:I prefer lighter lubes for most road and dry off-road conditions. I usually use TriFlow, mainly because its cheap, and it also works really well for cables. Other chain lubes don’t work as well on cables, so its just more convenient for me to have one bottle that does both. For wet/muddy conditions, I like thicker lubes that stick to the chain better, and form a barrier that helps to prevent water from getting inside the chain. Finish Line Wet works really well, but most “wet” or “extreme condition” lubes work just as well. Those also work well for dry conditions (and actually make the chain run quieter), but tend to attract more dust, so your chain may get dirtier. So I prefer to match the lube to the day’s expected riding conditions.
BC:How often should we lube our chain and how often should we clean/degrease our drive train?
Mike: For road, I lube my chain every 100 miles or so, while for off-road I lube it every single ride. The best method is to first wipe the chain down, and get it as clean as possible just using a rag. Then put a drop of lube on each link, then spin the crank backwards a few revolutions to work the lube in, then wipe the chain down. If the chain was really dirty, I’ll do this a few times. Its best to do this after a ride, rather than right before a ride, as that will give the lube a chance to flow into all the gaps in the links, and excess can run out. Then before the ride, wipe down the outside of the chain to get rid of any excess. If you do this regularly, the chain never really gets too dirty or gunked up, and removing the chain to clean it, or having to use solvents isn’t necessary. In fact, many of the chain manufacturers recommend never removing the chain to clean it, and to never use strong solvents. Most chain lubes have mild solvents in them, and can be used to clean the chain if it isn’t too gunked up. Nothing except chain lube ever touches any of my chains, and even when they’re almost worn out, they’re almost as clean and shiny as when they were brand new.
BC: What are your thoughts on WD40? Should that be used for chain lube?
Mike: WD40 actually isn’t a lube, its a solvent, and breaks down lube (The “WD” stands for “Water Displacement”). Its best used for cleaning up really dirty chains, but its best to never let the chain get that bad in the first place. If you do use it to clean up a dirty chain, you should immediately use a real chain lube to finish the job. Instead of WD40, I prefer to use TriFlow in a spray can, and spray it onto a rag until its soaked, and use that to clean up the chain. That works almost as well as a regular solvent, but lubes the chain at the same time as it cleans it, instead of removing all the lube.
