Today's Tech Tuesday takes a closer look at chain lube. There is a great video inside explaining the differences in lubes, as well as showing you the proper technique to use when lubricating your chain. If you think nothing of spraying your chain with WD40 then this is the Tech Tuesday for you! Inside you'll find information on:
• Which types of lube to use for your conditions
• What never to put on your chain
• How to properly lube your chain
Read on...
For a lot of riders it is a victory if they simply have some sort of lube on their chain, but using the right kind of lube for the conditions at hand can actually make a big difference to how your drivetrain performs. Applying the wrong kind of lube can cause all sorts of problems, from a gummed up and slow shifting drivetrain, to one that won't be quiet, but the end result is always accelerated wear that will cost you time and money in the long run. But that is only half the battle... How you lube your chain can have just as big of an effect, if not more so, than what lube you are using. You won't be doing yourself any favors if you are going to town with a can of spray lube and have shaky hands from downing too many energy drinks. In fact, you're doing more harm than good by overdoing it as excess lube will only attract dirt and grime. The key is to only apply the right amount in the right places.
Watch the video to learn all about lube and how to properly put it on your chain:
Types of chain lube
Teflon based lubes are by far the most common type of bicycle chain lube used, and for good reason. The name Teflon is actually DuPont's brand name for what is known as "PTFE" in the chemistry world, or
polytetrafluoroethylene. Teflon has an incredibly low coefficient of friction when used between two solid objects like chain plates and rollers and is used to lube much more demanding mechanics than our simple bicycle chains. In order for the PTFE to properly penetrate into the inner workings of a bicycle chain, as well as stick around long enough to be useful while still having self cleaning properties, it can be mixed with many kinds of oils and solvents depending on the conditions that it has been designed to perform best in. The general rule of thumb is that the thicker the lube is, the longer it will last in wet conditions, but the stickier and messier it will be. If you live in a rainy environment like we do here on the West coast of B.C. you will be best off using a thicker lube because it will last much longer and not require as many reapplications. If your home trails are dry and dusty, then you'll be much better served to use a thinner lube that won't collect as much dirt that would gum up your drivetrain and create a mess like a thick lube used in that sort conditions would.

The other common option are
wax based lubes. Just like Teflon chain lubes, wax lubricant can come in many different kinds of mixtures depending on the conditions that it is intended to be used in. Wax based lubes are generally thought of as a cleaner option to Teflon, but they have some drawbacks of their own. While they certainly collect less dust and dirt, you must be very conscious of how much wax lube you are using because it does have a tendency to build up and create a mess. Picture big globs of wax caught up between your pulley wheels and derailleur cage and you'll get the idea. Wax lubes also require the chain to be quite clean before you apply them for best results, and even then they won't last as long as their Teflon based competition.
There are all sorts of lubes and concoctions that you
shouldn't use on your chain, most of them are either two thin or two thick. One example would be the popular Phil's Tenacious Oil. It is the perfect lube for inside of freehub bodies, but far too thick and stringy to be used on a chain. While it would last much longer than standard chain lube, the mess and build up that it creates can be quite nasty. On the opposite end of the spectrum is the ever popular WD40... this is not a lubricant for bicycle chains! WD40 is far too thin and acts as a solvent that actually strips the chain of any lube that may be present. Use WD40 to free up old and rusty parts, but not to lube your chain. You are far better off heading down to your local shop to pick up some proper lube designed for where you ride. If you're not sure what to get it is worthwhile to ask.
Lubing your chain
I know a lot of you are happy just to have a chain that doesn't squeak and scare away fellow riders, but by properly applying lube to your chain you can limit the amount of dirt and trail grime that it picks up, which will increase chain life and cost you less money down the road. Oh, and as a side benefit your bike will also be quieter, shift better, and you'll be less likely to be that one annoying guy who's bike can be heard from a kilometer away. Below is how I like to lube my chain, your method may differ and there are countless ways to do it, but the goal is always the same:
to apply the right amount of lube to the right places. Step by step instructionsWhat you need: Chain lube and a rag.
 |
| Step 1. Begin by shifting the chain to the middle ring and a middle cog for a straight chain line. Use a rag to clean any dirt or grime that may be on your chain before you add more lube |
 |
| Step 2. I prefer to use a drip bottle as it is far more precise than an aerosol can |
 |
| Step 3. Apply lube sparingly to each roller on both the top and bottom sides of the chain while pedaling in reverse |
 |
| Step 4. Keeping it in the same gear while you pedal the bike for a few minutes to let the lube penetrate into the chain's inner workings |
 |
| Step 5. Use a clean rag to wipe off any and all chain lube that may be on the outside of the chain, including the side plates and the derailleur's pulley wheels. Extra lube will only attract dirt and create a mess. The only lube that you want on your chain is in the rollers and between the chain plates |
