The first part of a two-part video on how to clean a bicycle chain. In the process, it also demonstrates how to use chain cleaning products from Finish Line Technologies. For more bike maintenance tips, go to www.finishlineusa.com and www.maintainthatride.blogspot.com.
The grime you’re trying to remove from your chain can consist of oil, grease, lube, silt, sand, mud, salt, acids, bases, and any combination of these and other organic and inorganic soils. Some chain cleaning methods are most effective on the kinds of soils you find while riding on heavily trafficked roads, like oils, greases, acids, and bases. Others are more effective on the kinds of soils you find while riding trails, like mud, silt, and sand. It will save you a lot of time and aggravation to carefully consider what kind of riding you do, where you do it, and what kind of lube you use before deciding how to clean your chain.
A single link of a modern, or “bushingless,” chain consists of ten parts. Among other things, the design of a bushingless chain allows for an easier and more complete flow of lubricant through the internals of the chain than older designs using full bushings. However, the greater number of parts and the spaces between them also makes the chain more susceptible to contamination and subsequent wear.
The parts of the chain that are most susceptible to contamination are the insides of the rollers and the shoulders of the inner plates. The parts of the chain that are least susceptible to contamination are the outsides of the rollers, which are continually cleaned by contact with the teeth on the chainrings and cogs.
Never allow your chain to get so dirty that you no longer want to take the time to clean it and end up applying lube on top of the dirt. Most commercial grinding pastes consist of oil, like the oil that you apply to your chain as a lubricant, and silicon dioxide, or sand. Applying lube to a dirty chain is like intentionally grinding it down. If it’s left dirty for long enough, a chain can wear down the teeth on the cogs and chainrings so badly that a new chain, when put under pressure, will skip over the teeth. If this happens, you have to replace the cgoset and possibly the chainrings as well, which can often exceed the value of the bike.
Use Speed Clean Speed Degreaser and a rag to clean your chain if you don’t have time to fully clean your chain and the rest of your drivetrain, but don’t want to apply lube on top of a dirty chain. This method works especially well on the kinds of soils that result from road riding in wet or dry conditions, like oils, greases, and road salts, and is also great for removing old lube, including wax lubes. It doesn’t work as well on soils consisting of large particles, like sand. One concern when spraying a chain down with degreaser or lube and wiping it off is that grime actually gets pushed deep inside the chain, where it’s most susceptible to wear. Speed Clean, however, totally dissolves grime, has a powerful spray that blows dirt out of the chain’s internals, and dries within seconds, so that it doesn’t have time to leach into the chain.
Prepare the can for use by trimming the hose that comes with the can, then inserting it into the nozzle.
When inserting the hose into the nozzle, place one finger behind the nozzle to keep it from popping off when you push in the hose.
Brace the can against the seatstay and wheel dropouts. This will hold the can steady, allowing you to focus the spray on the chain, instead of missing it and spraying other parts.
Spray the chain while turning the crank backwards for about ten turns. Then place your rag in your hand, grip the chain with it, and turn the crank backwards again for another couple of turns. Lift the rag, move to a clean spot, and repeat the process until a minimum of dirt appears in the rag. Moving to a clean spot will keep you from running the chain through the dirt you just removed. You may find that the residue you’re wiping off is dry, not wet as you might expect after spraying the chain down with a liquid degreaser. This is because Speed Clean dries instantly, which has many advantages when used for other applications. However, the dry residue consists of fully dissolved grime, and will come off into the rag just as easily as if it were wet.
Wiping below the chainstay usually gives you more room to work and allows you to pull down on the chain, which places it under tension and opens up the links slightly.
Lube your chain after cleaning it to prevent flash rust from forming. This is especially easy with Speed Clean because, as we’ve already mentioned, it dries instantly, which means that you can apply lube right away, without waiting for the chain to dry. There’s a kind of lube for every kind of riding condition, like wet lubes for riding in wet conditions, dry lubes for riding in dry conditions, ceramic lubes for racing, etc. Many of these lubes are not compatible with one another, like oils and waxes, and can turn your chain into a dirty mess minutes after you cleaned it. If you don’t know what lube you’re going to use, Finish Line’s Dry Teflon Lube is a good choice. Its carrier fluid evaporates instantly, leaving dry Teflon particles and anti-rust additives which will not only work with other kinds of lube, but actually fortify them. If it turns out that you’ll be riding in dry conditions, you can just leave it on as is.
Wipe any dirty degreaser off of your rims. Earlier, we mentioned that Speed Clean’s fast-drying properties have many advantages for other applications. One of these applications is the cleaning of rims and disc brake rotors. If you get Speed Clean on your rims, it will not only wipe off easily, but will also remove any dirt and brake pad residue from the braking track, even if it’s already contaminated with dissolved grime from the chain. Unlike other degreasers, it won’t leave a slick film on the rim that might compromise braking or cause squealing. If you’re using a degreaser other than Speed Clean, wipe the dirty degreaser off of your rims, then pour a bit of alcohol into a rag, and wipe the rims down again, allowing time for the alcohol to dry before riding.
If you use a spray lube on your chain after cleaning it like we did in this video, wipe the rim off after lubing the chain, not before. Any Speed Clean that blew onto the rim while cleaning the chain will instantly break down any lube that gets on the rim, allowing you to wipe if off along with the dirty degreaser and brake pad residue.
