How To Service Your Pedals. GCN’s Guide To Servicing Look And Shimano Pedals
Lubricate the pedals without completely disassembling them
If you find that the pedals have become difficult to rotate, and there is no way to disassemble them at the moment, then lubrication without complete disassembly may be a temporary solution. For this, you can use almost any liquid oil. In my case, I used liquid oil for sewing machines I-20.
But let’s clarify right away that this is only a temporary solution; in the future, a complete lubricant change should be performed.
- We put the bike on its side so that the pedal, which will need to be lubricated, “looks” with its end straight up.
- Remove the plug at the end with a screwdriver (or other improvised means).
- Slowly pour liquid sewing machine oil (about 2 ml.) Into the pedal (you can rotate it slowly).
- Install the plug and, without lifting the bike, quickly rotate the pedal for 10 seconds.
- We put the bike on the wheels and pedal several times. It should spin easily and for a long time.
This completes the process of lubricating the bicycle pedal without completely disassembling it. Over time, liquid oil will still leak out of its cavities, and the problem will return. Therefore, as free time appears, you should still disassemble and replace the grease in the bearings.
Bicycle pedal bushings: disassembly, lubrication and repair
What to do if the pedals on the bike are stuck together, difficult to rotate, or not spinning at all? This is not such a terrible breakdown as it might seem at first glance. While some may look slightly different, most are almost identical. The differences mainly lie in the different form factor of the platforms, which can be not only different in size, but have special hooks for specialized cycling shoes. But the pedal hub of the bicycle on almost all models has the same design. Therefore, in this material, using an example, we will consider the questions of how to remove pedals from a bicycle, disassemble, lubricate and repair them if necessary. We’ll also take a look at the pedals and talk about which pedals are best for different bikes.
The form factor of this type of pedal is a monolithic wide platform made of aluminum or magnesium by casting or milling (although some of them are made of high-strength plastic). In fact, the body of the part is one whole product, inside which there is also a threaded axle, bearings, a washer and a locknut. They can additionally have reflectors and hook pins screwed into the body. The latter prevent the sole from slipping on the bicycle pedal.
The advantages of this type of pedal include increased durability, which is why they are often used on BMX bikes. Although they can also be installed on mountain, road and city bikes. Not recommended for road racing due to heavy weight.
Cons: slightly more expensive and heavier than classic pedals.
How to remove and disassemble bicycle pedals
Removing the pedals from the bike, for example, for replacement or repair (maintenance) is not a difficult task if you know how to do it correctly. The main trick here is that the left and right pedals are unscrewed differently.
The right one is unscrewed classically. counterclockwise, and the left, on the contrary. clockwise (has a left-hand thread). This is done so that the pedals do not spontaneously unscrew from the connecting rods while driving.
How To Service Mountain Bike Flat Pedals
You can remove bike pedals using an adjustable spanner, open-end wrench for 15, the so-called parrot key, or a specialized one for dismantling the bicycle pedals. It should be noted that the gap between the pedals and the crank is 12 mm, so you need to choose a tool that will fit between these parts. For further complete disassembly, we also need a set of socket wrenches.
After we have unscrewed the pedal from the connecting rod, we can begin to disassemble it. To do this, follow these steps:

- Remove the plug at the end of the pedal. To do this, pry it with a screwdriver or other thin, sharp object.
- Using a socket wrench, unscrew the locking locknut and remove the washer.
One of the most common types of bicycle pedals, it has a classic form factor, which we could see on old Soviet bicycles. Although modern models have undergone some restyling and received improvements in terms of pedaling comfort. They are quite reliable (with the exception of the cheapest Chinese bike pedals) and easy to maintain. They consist of: a body, inside which an axle, bearings, a cone, a washer and a locknut are located; two pads fixed on the sides of the body with bolts; reflective reflectors can be optionally present. Industrial bearings can be used instead of bulk bearings. Also, the body for these pedals can be made entirely of plastic, representing a monolithic structure.
They can be used on almost all types of bicycles, from mountain bikes (MTB) to road bikes, although they are very rare on the latter. The only place where their use is not advisable is on stunt bikes, or as they are also called BMX bikes, as well as on bicycles for freeride and downhill. The latter is due to the fact that during various jumps, the pedals experience very significant loads, which they may simply not be able to withstand.
The advantages include the prevalence, light weight (since they can be made of plastic), cheapness and ease of maintenance.
Why lubricate your bike
Grease for the bike, chain and chassis, first of all, is needed for the “iron horse” to last longer.
Bicycle parts, which are related to the chassis, require lubrication in the first place, since they are responsible for the movement on this vehicle, they are combined into a system:
- the chain is considered the main part of the bicycle. It provides the bike with movement, so the quality of the lubricant affects the technical condition of the vehicle. The signal that something is wrong with her is the ringing that appears. It is necessary to take into account, in addition to lubrication, its natural wear. This part requires replacement after 1.5 thousand kilometers traveled;
- the axles of the brake system are also important for the timely stopping of transport and safe movement;
- roller wheels responsible for tensioning the chain, i.e. opposing weakening;
- the gear selector includes forward and backward. The first is responsible for shifting speeds, the other for increasing speed. Lubrication and competent maintenance help these parts to perform their functions without fail;
- brake and shift cables. Bicycle lubrication is important to these brake commanding parts because they integrate and induce the parts involved in shifting and braking. To lubricate the cables, it is enough to drip oil at the outlet and inlet, press the switches several times and the pedals;
- carriage assembly. In this unit there is a special cup that keeps the bearings from falling out, and the pedals from scrolling, which helps to turn them easily. Therefore, lubrication is essential for safe cycling;
- wheel bearings also need lubrication. Their function is to keep the wheels from “loosening” while driving, to help light torsion;
- shock absorbers. Thanks to them, the bike moves smoothly. In addition, they soften the impact when the wheel hits obstacles and resist vehicle breakdown. In order for them to perform their functions effectively, you need a bicycle lubricant, which is applied to the rear shock absorber and the front fork.
If the bike owner lubricates the bike. the chain and the listed parts in advance, there will be no problems, and the service life of the bike will increase significantly.
What to use to lubricate your bike
There are a huge number of oils and lubricants on the market suitable for this purpose:
- liquid oils belong to the category intended for lubrication of all types of chains, which ensures their reliable operation;
- two-component aerosols are used to lubricate: switches, cables, threads. When spraying aerosols, the oils contained in their composition penetrate into hard-to-reach places, providing lubrication of parts that cannot be processed in any other way. Some aerosols contain kerosene, so they are an effective assistant for separating worn parts (“LM47”, “LM40”);
- plastic lubricants are used if you need to lubricate or seal any kind of connections. Some contain calcium. They are used as a lubricant for joints and assemblies. This type of bicycle lubricant includes: “Unitol”, “Solidol”, etc. Their advantages include the ability to stay on the elements for a long time, ensuring their efficient operation. Another type of plastic grease for a bicycle is grease with lithium: “Fiol”, “Litol. 24”, etc.
- chassis elements retain their characteristics for a long time.
Teflon bicycle grease has high performance:
- being between the moving parts of the chain, it is not subject to friction;
- needs thinners for better penetration;
- applied in a thin layer.
Silicone bike and chain lubricant is resistant to wear of chain elements. Dust does not “settle” on it. Apply it not in a thick layer.
Lubricants containing wax. They are effective, applied in an extremely thin layer to prevent plugging of bushings and links. The part is thoroughly cleaned before application. They are inferior in performance to Teflon bicycle lubricant, but they are quite effective.
How to lubricate the carriage
Lubrication of the carriage on a bicycle is done by simply placing grease in the cups and on the surface of the bearings, on the bushing, and by distributing them evenly. In addition, before lubricating the carriage, it is advisable to thoroughly wash the bearings and all cavities, the surface of the bushing, for example, with kerosene. It is flushing that will subsequently make it possible to properly lubricate the carriage.
How often the shock absorbers are lubricated
The principle of their disassembly was described above. It remains to learn that you need to lubricate the shock absorbers daily if you ride in the rain and weekly in the sun. It is recommended to use aerosol and oil lubricants.
Front and rear derailleurs
The continuity of the cycle depends on the clarity and consistency of their actions. Sometimes, especially when going uphill, switching should be done immediately after the afterburner, in order to change gears not in tension, but on free speed. It often takes fractions of a second, and the switches must work flawlessly so that the upward movement does not “get bogged down”.
Switches are ideally disassembled for lubrication. details about maintenance and lubrication can be found here:
Main run carriage
We can say that this is the “main” axis of the bicycle. It is from her that the impulse is “distributed” to other elements. Therefore, the speed, ease, and comfort of the stroke depend on the state of the carriage. The carriage elements are:
A different, “thick” grease is put into the carriage, not the one that drips onto the chain or cables.
