Top 4: Maxima 55901 10WT Standard Hydraulic Fork Oil

This new brand arrives with a high-performance product that provides excellent hold. Its composition based on wax and water offers the particularity of being applied and in a long-lasting way. Its qualities are many since it prevents the accumulation of dirt on the bike chain.

It is also resistant to vibrations and aggressions that we encounter when cycling in hard conditions such as in the rain or mountain biking. The resistance over time is well above average. We had checked more than 400kms in the dry without needing to add lubricant. Another advantage of this lubricant is that it considerably reduces the operating noise of your transmission. Besides, it is 100% biodegradable. Its implementation requires a few precautions which are valid for all lubricants, namely a perfectly degreaser and clean chain. For maximum efficiency, apply the first coat and let it dry for a few hours. You can apply a second coat and go for a ride. It is an effective product that offers excellent value for money and protects the environment.


  • Resistant to vibrations and aggressions
  • Reduces the operating noise
  • 100% biodegradable


  • Expensive

Top 5: Muc Off Dry Chain Lube 112 Milliliters

This high-end bicycle lubricant comprises fluoropolymer and ceramic nanoparticles. It also offers resistance over time in severely dry conditions, at least 500kms. In the rain, you have an autonomy of 80 to 100kms. The cleaning is easy because a simple cloth is enough. In the event of significant contamination, it is preferable to use a degreaser.

The outstanding advantage of this lubricant is the attenuation of chain noise. In the first application, the operating silence is perceptible. Finally, know that this product is biodegradable and does not use petroleum products.


  • Fluoropolymer and ceramic nanoparticles
  • Resistance over time
  • Attenuation of chain noise


  • Expensive

Top 6: SRAM RockShox Suspension Oil Bottle

The most durable lubricants are not just cleaned with water, but require chemical cleaning products. While it can be a headache when cleaning, it is a plus if you live in a wet area as the chain lubrication will last much longer.

If you are looking for a long-lasting lubricant, SRAM RockShox Lubricant will do the trick. They manufacture it for bicycle chains and cables that are mainly used in humid environments. With this lubricant, your bike will be dust-free and will not absorb all kinds of contaminants on the road.

  • Adheres to the chain during application
  • Reduces cable splatter
  • Prevents the chain from stretching


  • Long time to dry

Why Should Buy MTB Fork Oil

It relates one of the most confusing issues in the world of suspensions to the use of oils. Oily lubricants for suspensions are divided into two large macro-categories with different functions and are classified according to parameters that are not always clear.

Figuring out which oil to use in a situation can be nerve-wracking. Suspension oils are among the most complicated aspects of this fascinating world. Sometimes, it is easier to learn how to overhaul a fork than to understand the differences between the oils.

Who Should Buy MTB Fork Oil

The term “viscosity” shows the ability of the molecules of fluid to slide over each other. The more these molecules can slide over each other, the lower the viscosity of the fluid itself. To give a trivial example, water is certainly less viscous than oil.

In the world of suspensions, the viscosity of the oil is a crucial characteristic, since the fluidity of the mixture will perform the suspension. A viscous oil will be more difficult to circulate through the orifices, thus generating a different compression and return than low viscous oil.

We can identify the viscosity of the suspension oil through a grade called ISO VG. It is standardized and shows the molecular viscosity at a temperature. The operating temperature is decisive for modifying the viscosity of the oil.

Some oils become more fluid when the temperature increases, while others become more viscous. For this reason, the viscosity of a suspension oil is usually determined through a graph. It indicates its density at the various operating temperatures.

The ability to change the viscosity of an oil is called the VI (Viscosity Index). The lower the viscosity index, the greater the ability of an oil to change its fluidity as the temperature varies. Lubrication oil is usually less viscous than a hydraulic one. It is because the oil must flow easily into the chainstays to lubricate the entire system.

Best MTB Fork Oil FAQs

What kind of lubricant should I use?

You can decide which one to choose for different types depending on what you want. To give you a simple idea of ​​what each is, let’s look at each of them.

Wet lubricant is one of the most popular ATV lubricants. This lubricant can withstand wet and even muddy conditions. How they do the job is pretty straightforward. It helps protect the water from coming into contact with the links.

Wet lubricants are thicker and have a lower viscosity level than dry lubricants. It might come with some issues. Dirt can easily get stuck in the lubricant, which can cause chain wear.

Dry lubricant is an alcohol-based lubricant designed for dry conditions. This lubricant can protect your chain from debris much better than wet lubricant. However, they do not offer the best level of protection against water.

What is the reapplication time of MTB oil?

During the entire selection process, also consider the reapplication time of the lubricant. Normally, the reapplication time mainly depends on the type of lubricant you choose. The way you ride your bike may also dictate the reapplication time.

We have some lubricants that work best when you lubricate more often. Others have been worded so that you have to reapply after six months or even once a year. However, if you take your ATV every day and especially in very harsh conditions, it is advisable to lubricate it more often. It will ensure you get the highest level of performance.

How to apply lubricant and take care of the bike chain?

After spending a lot of money buying the best chain lubricants on the market, you will also want to know how to use them. You may also want to know how to maintain the chain, as this will ensure that it will serve you for years to come.

Cleaning is the first thing you should do before you do anything else. Armed with a rag and a decreasing agent, clean the area to be lubricated. Ideally, remove most of the dirt and grease from your chain before applying the lubricant. You can take things a little higher and use a chain cleaner to deep clean them.
