How Do You Know When to Oil Your Bike Chain
Cleaning the chain on your bike is a primal part of reducing wear, improving operation and showing love to your bike. This is the ultimate guide to cleaning cycle chains, and likely contains more nerdy info than you lot bargained for.
Your bike chain will wear for various reasons, but the key accelerant is grit within that grinds away the metal. While reducing wear through chain cleaning is certainly the factor that will save you lot money, y'all should also consider the efficiency that's lost through all that abrasive friction.
Why should I make clean my wheel chain?
Jason Smith, of independent testing facility Friction Facts, confirms that at that place's a measurable amount of efficiency lost from a dirty chain.
"The numbers can vary based on the 'dirtiness' of the concatenation, but on average, testing shows a dirty road chain can decrease efficiency by about 3 to 5 watts (at 250-watt rider output) – about one to 2 per cent of power loss," he says.
"For example, say a properly cleaned and lubed chain consumes well-nigh 7 watts. The lite road grit kicked up from a couple of 'clean' road rides can price an additional 3 watts of frictional losses."

Don't permit your chain get this dingy, it will just wear out your other drivetrain components. Colin Levitch / Immediate Media
Smith explains that number increases with the dust: "Riding on several route rides without cleaning or relubing tin can cost about 5 watts of losses. In extreme cases (MTB or cyclocross for example), nosotros've seen a muddied chain add together 12 watts of losses over baseline.
"When a chain is not properly cleaned and lubed, friction levels increment at the sliding surfaces of each concatenation link. At 95rpm with a 53t front end band, 40,280 chain link articulations occur every minute [an articulation is a link bending into or out of a ring, cog, or pulley] equally the chain snakes through the drivetrain. Considering of the high number of links constantly articulating, it is crucial to brand sure the friction is minimised within the links."

Whether or non you lot need to split your chain depends on your drivetrain. Jonny Ashelford / Immediate Media
Reading through various how-tos and forums, everyone has a slightly different view on whether the chain should be on or off the bicycle for a thorough cleaning.
Removing a chain from the wheel and shaking it in a jar of degreaser used to be mutual exercise, but not so much anymore. With chains becoming more precise every bit farther gears are added to mod drivetrains, our techniques for cleaning have had to adjust.
When 10-speed drivetrains were commonplace, the bondage were typically designed to go on once and then removed only when worn out.
Calvin Jones of Park Tool expands on this, saying that "if the chain has a 'connection rivet', you invite creating a weak link every time you remove and install a new connexion rivet. Fifty-fifty a master link is best left alone.
"The improve master links… 'click' into place, and taking it off and on and off and on removes this feature. Once more you are creating a weak link."
For those with (officially) non-reusable links, SRAM and Shimano recommend using a brand-new joining link every time a concatenation is installed.
Withal, many riders re-use such 'snap-lock' links with success, despite that, brands insist against information technology. If you do decide to take the risk, a pair of chief link pliers is the perfect tool to force these gratis.
For older drivetrains, using seven, viii or 9 speeds (or those with re-useable 10- or eleven-speed links), and so this may be open to more debate.
Here, chains from KMC, SRAM and Wippermann tin exist easily removed from the bicycle and re-installed via the supplied quick-link.
My chain needs to stay on – now what?
Tom Marvin / Immediate Media
The majority of bike maintenance product brands, including Park Tool and Muc-Off, recommend the use of a chain-cleaning device.
Hither, the device includes rotating brushes that work the degreaser through the chain in a controlled mode as information technology is dorsum-pedalled past. Feel shows they're all pretty similar in part, and build quality is all that really separates them.
Jones of Park Tool takes information technology a stride farther and recommends the employ of a 'dummy hub' (aka concatenation keeper) in place of the rear cogs.
This is done specifically to avoid running degreaser through your freehub and rear hub bearings, and is common practice among WorldTour race mechanics besides.
A side do good is easy access to the derailleur pulley wheels, a notorious spot for gunk to build.
If your bike has disc brakes, then removing the cycle volition also ensure oil-filled degreaser stays off your disc rotor. Taking it a stride farther, you can use a plastic bag and elastic band to seal your restriction caliper.
"After using a chain scrubber, with a degreaser, follow up with a second launder of warm soapy water. Using 2 dissimilar solvents flushes out whatever grit that is left," suggests Jones.
Colin Levitch / Immediate Media
Smith of Friction Facts agrees with Jones and Sampson that using a chain-cleaning device is the best answer if the chain must stay on. However, he warns of potential problems when doing so: "Start, the chain cannot exist submersed in cleaning fluid."
The tension of the chain is another gene to be aware of, continues Smith: "Even though the tension is low-cal [created past the rear derailleur cage leap], the positive tension does not let the chain to get slack. A slacked chain opens up the sliding surfaces and allows cleaner to flow through the internals more freely than a tensed chain."
Whether you lot use a stiff-bristled castor, a concatenation cleaning device or the ugly sweater you got for Christmas, it's best to practice it outside. Chain cleaning is a dirty task and doing it over carpet or indoor floors isn't advised.
Jones too warns against using harmful degreasers, stating that you shouldn't apply diesel, benzene, gasoline or acetone. At that place are enough of safer and healthier options that will get your chain suitably clean.

And don't be tempted to utilize a ability washer every bit a chain cleaner – "unless you are ready to overhaul the wheel at the same time," cautions Jones – because these can strip the grease from your bearings if you bespeak them in the wrong management.
I tin can remove my chain – how should I make clean it?

Ultrasonic cleaners tin can be bought online relatively cheaply – if you're paranoid about dirt, this is the right tool to have. David Rome / Immediate Media
If you lot take a re-useable masterlink in your chain and don't need to touch that concatenation breaking tool, you're in the minority, but this means you tin can accept that chain off and run it through a degreasing bath.
Jason Smith is all for cleaning chains off the bike. "We recommend removing the chain to properly make clean it. A quick link such as the Wippermann Connex Link facilitates easy removal. The near effective method of cleaning is by placing the chain in a unproblematic and cheap ultrasonic car.
"The ultrasonic agitation does a dandy chore of removing dirt and grit from the internals of the links. If an ultrasonic cleaner is not available, the chain can be placed in a sealed container with cleaner and shaken vigorously," Smith suggested.
In our experience, using Elementary Green in combination with an ultrasonic cleaner has proven constructive at getting the chain make clean and most chiefly, getting the stubborn dust out of the rollers. Nonetheless, doing this on a filthy chain takes a number of 5-minute cycles (or longer) before the chain is spotless.
If y'all don't have time for this, scrubbing down the concatenation will get almost the aforementioned results of the ultrasonic cleaner and you can have it dorsum on the bike far quicker.
If you lot want to speed upwards the process of using the ultrasonic cleaner, scrub the chain with a stiff-bristled brush to bring back the exterior sparkle, then run it through the ultrasonic cleaner. Once done, rinse it with water and and so air dry out with compressed air. You will then have a truly sparkling fresh chain.
Whatever y'all do, don't leave your chain to soak for an extended flow of time (days). There are some horror stories out there near degreaser corroding metal and causing surface cracks.
The lazy manner to clean a bicycle chain

Lube over that grit! Even if it creates a grinding paste, testing from Friction Facts shows lubing a dirty concatenation is more efficient than a dry dirty concatenation. David Rome / Immediate Media
If you lot don't desire to get to all of the hassle of deep-cleaning your chain, lubing and wiping it regularly with a clean, lint-gratuitous cloth will suffice.
Some lubes claim to be an all-in-1 cleaner and lube, simply we've found these to be too thin for proper lubrication over longer rides. However, the practice is the aforementioned with any lube – wipe off the backlog before you ride.
Smith agrees with such exercise, stating that it'due south better to lube over a dirty chain than non lube at all.
"At a minimum, a rider should re-lube the concatenation prior to every ride, even if they are re-lubing over a dirty chain. For efficiency, information technology's better to re-lube over a muddied chain than practice nothing at all," suggests Smith.
If you follow up this communication with running the concatenation through a clean rag, you'll likely stay on top of many dirty chain woes.
Prevention is mayhap the best thing in order to be lazy. Jones suggests: "First, utilise less oil as you lubricate. Don't soak a chain in lube. Use a drip lube and put a drib along each joint, each link across the roller. Hosing your chain with spray certainly gets lube there equally well, but it as well gets it all over side plates, making the concatenation a dirt collector.
"Information technology takes more time to lube each and every rivet simply it also lets you inspect each one, and that will assistance you take hold of that 'weak link' of a burred, bowed or bent side plate, a mis-pressed rivet and a tight link," Jones adds.
The laziest way to clean a filthy chain is just to replace it. Hither, Jones offers the unproblematic communication to measure for concatenation wear before each cleaning – at that place's no point wasting time on a worn chain.
Once a chain is showing signs of wear, nosotros pull the quondam cassette and cranks off the bike and requite them a proper cleaning in a parts washer. Doing this provides a nice welcome for a fresh concatenation.
Tin can a chain be too clean?
Some people believe that cleaning a concatenation also much removes hard-to-replace factory grease from within the rollers. While it is important to ensure a chain is correctly lubricated, there's trivial risk of a concatenation being too clean.
"We don't feel a concatenation can ever be besides make clean, as long as it'southward properly lubed after cleaning," reports Smith. "In fact, when Friction Facts was in the business of treating chains [the UltraFast Optimization procedure acquired past CeramicSpeed] we stripped the chain completely using heavy solvents. The goal was to attain a bare metal surface, prior to the lubrication treatment."
We asked Jones the same question, for which his answer was but: "No, but at some betoken, you are cleaning but for the fun of information technology."
One time the chain is clean, Smith warns non to wait too long subsequently cleaning before applying lube: "This minimises oxidation of a dry chain."
Friction Facts
Then what well-nigh the lube itself? Are factory-practical ones superior?
"We've debunked the claim that aftermarket lubes tin't get as deep into the chain as factory-applied lubes," says Smith. "Based on the friction disuse seen during testing, it takes i minute or less for a drip lube to fully penetrate the internals of a rotating concatenation."
Smith says he's done many tests on chains with factory lubes and aftermarket ones: "Some factory lubes are faster than other factory lubes, and we've even seen a v-watt swing between the fastest and slowest aftermarket lubes. However, in no case have we ever seen a factory lube outperform the fastest aftermarket lubes."
Alright, and then it's clean. Now what?

"Part of the full cleaning process is re-lubing. Choosing a high-efficiency chain lube is the easiest and least expensive manner to subtract friction in a drivetrain," says Smith.
According to Smith's testing, there's upward to a 5-watt difference between the pinnacle performing and everyman performing drip lubes. "Some of the top-performing drip lubes nosotros've tested are Squirt Lube, Lilly Lube, Stone-N-Roll Extreme, and Morgan Blue Rolls Pro.
Simon Bromley / Immediate Media
"Paraffin wax blends (such as Molten Speed Wax) are generally faster than baste lubes, but the application is more complex. As an option, a few companies are now providing paraffin wax optimised chains, ready to go," he says.
