The chain is one of the most stressed parts of a bicycle. It is in constant motion, works under pressure and faces dust, water or mud. Proper chain lubrication is therefore key to a long drive life, quiet operation and efficient power transmission. The main choices are oils and waxes, each with its own advantages depending on the riding conditions.
Bicycle chain lubricants come in a variety of forms, including oils and waxes. Choosing the right one for your needs depends on riding conditions and personal preference. Chain oil, designed for wet and muddy conditions, is thicker and more viscous, providing long-lasting lubrication that resists water and dirt. Wet lubricants are ideal for riding in the rain or off-road, but may require more frequent cleaning and reapplication. Dry chain lubricants are thinner and are designed for dry or dusty conditions. They are applied to the chain in a liquid state, but dry quickly to a waxy or dry film, reducing the attraction of dust and dirt. Dry lubricants are great for dry weather, but may not provide as long-lasting lubrication in wet conditions.
Can I combine different types of lubricants?
It's not ideal. For example, applying wax to oil won't work because it won't stick. The chain needs to be completely degreased before switching between different types of lubricant.
Why does my chain quickly dirty my cassette and derailleur pulleys?
You're probably using too much oil or not wiping off the grease residue after application. Excess oil traps dust and dirt, which then spreads throughout the drivetrain.
How do I know if the chain is dry and needs to be lubricated?
Typical symptoms:
- The chain whistles, squeaks or makes metallic noises.
- It is completely dry and rough to the touch.
- Deteriorated gear shifting.
- Visible dirt or rust.
Can I use WD-40 to lubricate a bicycle chain?
WD-40 multipurpose spray (classic) is not suitable as a long-term lubricant for a bicycle chain. It can be used for cleaning or temporary lubrication, but it evaporates quickly, does not protect the chain sufficiently and cannot withstand the load of riding. For regular lubrication, it is better to use specialized bicycle lubricants.
Chain lubrication: before or after riding?
It is best to lubricate your bike chain after a ride, not before. The lubricant needs time to settle and penetrate the chain links. If you lubricate the chain after a ride, it will have time to be absorbed well, and you can wipe off the excess lubricant before the next ride. This will prevent unnecessary dust and dirt from collecting. Lubricating just before a ride is not a mistake, but it can cause the lubricant to remain only on the surface and be unnecessarily sprayed during the ride.
Can an overly lubricated bicycle chain be a problem?
Too much grease causes dust, sand, and dirt to stick to the chain, creating an abrasive paste that accelerates wear on the chain, cassette and chainrings. Excess grease can also splash onto the frame, wheels or brakes, causing fouling or reducing the effectiveness of the braking system.
