SAE viscosity classification of motor oils. The more viscous (thicker) the lubricant is, the more it will be resistant to water washout, but it will also attract more dirt. Bicycle chains do not need multi grade SAE (stands for Society of Automotive Engineering and automotive temperatures do not apply on a bicycle) as bicycles chains operate at ambient temperatures and are directly exposed to the environment but you dedicate literally a third of this paper to SAE multi-grade standards. 5.1. Remove the seat post, wipe off any grime from the post and inside the frame. In plain English, the higher a viscosity of a fluid, the “thicker” it is. It may still be better than another lubricant that isn’t resistant to water washout, but viscosity has a significant effect on a wet lubricant’s characteristics and performance, besides the lubricants inherent characteristics. Livraison rapide Produits de qualité à petits prix Aliexpress : Achetez malin, vivez mieux Dry lubricants that are still a little wet8. So look at the given data more in terms of guidelines… I think not even computer software companies make better disclaimers than this. How does a chain get longer when worn? It is noted by Greek letter nu (ν), and measured in m2/s, though in practice mm2/s order of magnitude is often used. Coat the cables thoroughly with T-9 on your fingertips. 5.4. Liquid then evaporates rather quickly, usually after 2 to 4 hours, leaving a dry (or almost completely dry) film of lubricant. The reason it will be explained in this post is because for lubing a bicycle chain with oil, it is important to know how viscous (i.e. Make sure all of the solvents are evaporated and the chain is dry and then lubricate and put back on the bike. They are easier to find in smaller packages than turbine oils. Hydraulic oil. Unless paraffin wax is bought, melted by heating, chain submerged in it, let to drip dry, excess rubbed off… then a “special” dry lube for chain needs to be bought, with a fluid solvent that dries off and a rather high price. While paying someone to check all my writing is not a reasonable option for me. 8.1.1. As far as viscosities go, SAE 30 is a decent summer candidate (“thinning” with diesel per one’s taste), while SAE 10W is OK for the winter (also with “thinning” if required). Gear housings are often made of aluminium. Often, completely needless additives are noted, such as “EP additives that enable the lubricant to bear extremely high pressures…” – which are completely irrelevant for a bicycle chain lubricant, since it doesn’t face extreme pressures, no matter how hard one pedals. Classification of viscosity for motor and gear oils was made by USA organization SAE (Society of Automotive Engineers) and SAE viscosity classification is often used for automotive lubricants. This bike lube flushes out the dirt and grime exceptionally well, with many users noting just how much gunk came off their bikes during their first use. Quotation marks are because “ceramic” lubes are usually ones containing boron nitride synthetic ceramics (of a hexagonal crystal structure). Fine machine oil, of a relatively low viscosity (usually ISO VG 15 to ISO VG 25). Label usually says something along the lines of: “wax based chain lubricant”. How to change a particular lubricant’s viscosity (home brew). 7.5. not sticking dirt to itself and thus making the chain dirty. ISO VG viscosity classification. This will help when you go to remove them later. Dry lubricants for bicycle chains. Multi grade oil: A dry lube is applied as a liquid, before drying out to the leave the … The importance of chain cleanliness is explained in chapter 3. Fine paraffin oil is not a champion of water, or corrosion resistance, but it is very clean. Another thing to consider is that viscosity changes with temperature change. remaining between the pins and the rollers, without leaking out, as long as possible. Chain needs to be clean of any dirt or other lubricants, before applying them, so they can stick to it well and prevent dirt from sticking to it. While it has good characteristics for reducing wear of parts that are subjected to extremely high temperatures, for lubricating bicycle chains there are cheaper dry lubricants with good enough normal temperature characteristics. This is the best wet chain lube you’ll find on the market. (Sewing) Machine oil. Paraffin wax. Loads that bicycle chain bears are relatively low. Monograde engine oils, with SAE 10W, or even SAE 30 viscosity, thinned down with diesel fuel (from 4:1, to highly thinned in 1:4 ratio), can be decent bicycle chain lubricants. Some of these have been mentioned in the previous chapters, but this chapter “deals” with all of them together: lubricants marketed and sold as “bicycle chain lubricants”. FREE Delivery on your first order of items shipped by Amazon . 5.4. This can be impractical if a chain needs re-lubing, but one needs to go riding immediately. There are countless types and models: “dry bicycle chain lubes”, “wet bicycle chain lubes”, “dry, ceramic bicycle chain lubes”, “wet ceramic bicycle chain lubes”, and so on…. Listen for squeaks while riding, this will indicate a need for lubrication and cleaning. Some commercial paraffin wax based chain lubricants often have other dry lubricants added (usually PTFE), in order to improve characteristics. Using a clean rag applies a very thin layer of grease. for the first one, c.5.2. PTFE Additive. Gear oils, especially those with GL-5 specification, (and many other oils, like diesel) are corrosive to yellow metals at temperatures ~>80°C. Diesel will evaporate more quickly, but only after the lubricant has reached the important area between the rollers and pins. However, I’ve also provided a cross reference for comparing SAE and ISO VG grades, as well as explained the limits of SAE nomination (primarily the temperatures at which the SAE viscosity is measured). Much like one can call water hydrogen dihydrogen monoxide to be appear that you’re in the know – much of this paper goes to serve the same purpose. 5.3. However, these shortcomings are not severe enough to make (much) measurable difference from other oil types. Comments for robotsPlease remove this comment to prove you're human. So they are not good for rainy riding conditions. Wipe off the excess to prevent attracting more dirt. If you want to buy a customized bike, click here. Construction of a bicycle chain2. Picture 2 shows parts of a modern bicycle chain. If a bicycle is ridden just after applying dry lube, the lube will fall off the chain more quickly and attract more dirt – beating the purpose of using a dry lubricant in the first place. Rotate the pedal slowly and look closely at the individual chain links checking for dirt and rust. Slide them along the cable until well covered. for the second and so on. Chain wear measurement5. Note the lack of bushings as the main difference. That is why, to minimize wear, bicycle chain needs to be well lubed and as clean as possible (practical). Different weather cycles will call the various lubricating mechanisms especially if you ride in extreme weather. There's no set timeline for how often you should lube your chain. Without oil, you will have poor shifting performance because the cables won’t glide through the housings smoothly. Graphite is the first that comes to mind – it is cheap, and even has good high temperature stability as well, though the latter is irrelevant for bicycle chain use. Standard bike grease will work fine for this application or you can use an anti-seize or anti-slip formula. The lube will work itself into the chain. Shortcoming of paraffin wax is that it isn’t mobile enough to replentish lubed surfaces after being displaced, while not being strong enough to resist being displaced after put under pedalling pressure. (PTFE), some dry lubricants, even after applying them to the chain and leaving to dry, remain a little liquid, a bit “oily”. For most part, I’ve just used the name (like “water resistance” for example). Vice-versa – “thin” (low viscosity) lubricants usually don’t get as dirty, but are more easily washed out by rain. SAE viscosity classification defines two viscosity grade series: one with a “W” mark and the other without it. Take another clean rag and dry the chain. Fortunately, your contribution is an example of what I’ve seen over the years – people willing to contribute, and help the improvement. Unfortunately however it’s not quite that simple. Sports & Rec + Bikes + Bike Tools & Maintenance + Bike Lubricants & Greases; Skip product filters. All the information provided in this article, as well as on all of my websites, is to be taken as: “to the best of my knowledge”, or “as far as I know”. Bike Chain Oil & Lubricant. 6.3. Disclaimer1. Good rust protection and resistance to water wash off. These types of cyclists think of oil for bicycles like how a connoisseur thinks of wine; demanding only the finest quality lubricant for their bicycles. 60ml MTB Road Bike Chain Lube Bicycle Lubricant Silicone Oil Cycling Accessories Protects Against Wear Rust Dust. After diesel (partially) evaporates, lubricant will go back to almost (but not completely) it’s factory viscosity, being “thicker” between the rollers and pins, making it last longer and a bit more resistant to water washout. Then you can easily apply the lube to your bike chain. to get in between the pins and the rollers. In addition … Beyond being imperative for the performance and longevity of your bike’s drivetrain, oil allows bike chains to retain flexibility and decreases the amount of wear and tear. Rust prevention? You add so much superfluous information in an attempt to build credibility that anyone who actually understands these things knows you’re full of it. They usually come in “medium thick” grades – ISO VG 32 and ISO VG 46, but are produced in viscosity grades from ISO VG 15 to ISO VG 100. Factors that affect chain wear4. For those finding it needles, they can just skip the chapter. One of the more popular mountain bike chain lube types, the ProLink Chain Lube from Pro Gold Products, works to clean and protect your bike chain from rust and debris. Choose a lube that’s right for your bike based on the conditions you’ll be riding it in. Looking for all-weather protection for your bikes important elements? 01. Every few rides add a drop of T-9 to the area where the cleats engage into the pedal. Like it was explained in this paragraph, paraffin wax doesn’t flow back once it is displaced. 8.2.6. _g1 = document.getElementById('g1-logo-mobile-inverted-source'); Finish Line e-Bike Chain Lube™ E-Bikes place high demands on their drivetrains that differentiate them from standard bicycles. Viscosity is not a constant, but inversely proportional to temperature. Properties similar to turbine oils (in terms important for bicycle chain lubrication). It doesn’t leave stains, and it’s relatively easily washed even from clothes. _g1.classList.remove('lazyload'); You can also use a chain wear tool to see if it needs to be replaced. _g1 = document.getElementById('g1-logo-mobile-inverted-img'); Chain oil, chain spray, grease and lubricant for your bike can be found in a large selection in the r2 bike shop. 8.2.7. Boron nitride has a very high price. You can also subscribe without commenting. _g1.setAttribute('src', _g1.getAttribute('data-src') ); Without oil, the pulleys won’t rotate freely, you will also notice an annoying squeaking sound that seems impossible to find. Diesel viscosity is usually around ISO VG 3 grade. Here are useful tips on how to properly oil bicycle chains. Keep going until it is clean. Choice of optimal thinning method and lubricant viscosity is up to each user – depending on the riding conditions and chain maintenance “strategy”. International organization ISO (International Standards Organization), in coordination with ASTM (American Society for Testing and Materials), DIN (ger. Gear oils usually have EP (Extreme Pressure) additives. if ( localStorage.getItem(skinItemId ) ) { Never use something like WD-40 to lubricate your bike, only use a product designed for bike chains. There are special “summer” versions of chainsaw oils, with viscosity around ISO VG 160. After years of experience and experimentation, dozens and dozens of chains worn and replaced, I have come to some conclusions on the subject, which I will share in this blog. and the amount of dirt that gets stuck to the lubricant (c.5.3.). if ( localStorage.getItem(skinItemId ) ) { Dry lubricants are most often made based on paraffin wax, or PTFE (“Teflon”) lubricants. As an Amazon Associate I earn from qualifying purchases. Kinematic and dynamic viscosity: This is an industrial oil. For good lubricants use something light and waterproof like Boeshield T-9 Waterproof Lubricant. Loads that bicycle chain bears are relatively low. It has very good resistance to water contamination, water washout and provides excellent rust protection. Would this be useful for lubing a bike chain? Trade offs are given in table 3. Bicycle chain’s function is to transfer pedaling force from the front chainring to the rear sprocket. The dry lubricants are usually suspended in some sort of liquid, or solvent, that allows them to flow between the chain pins and rollers. I suppose. Also, chain needs to be completely clean and dry before lubing, so that paraffin wax can stick to it and prevent dirt from sticking to it. Again, you put forth a massive chunk of text and still don’t even address your own “Characteristics that a chain lubricant should poses.” It really goes to show the level of credibility people should put not only on this article but the entirety of the blog when you come out with these definitive papers (backed by a “dr of metallurgical engineering) yet are full of these massive gaping holes. They provide good rust protection and very good resistance to water washout. The outside of the chain should be cleaned as soon as the (diluted) lubricant is applied – before the solvent dries. ™”  After explaining viscosity, which is very important for liquid lubricants, a few words about dry lubricants for bicycle chains. Kinematic viscosity is the ratio of dynamic viscosity to density (specific gravity) of a fluid. Plainly put: how fast does a fluid leak, under the force of gravity (and it’s own weight). Water washout resistance and amount of dirt attracted depend mostly on viscosity, like explained in chapter 8.1. and table 3. That is why a worn chain is often referred to as “stretched chain”. Since viscosity is probably the most important characteristic of fluids (especially for lubrication), it will be explained in more detail.
