Hello bikers!
Here we are with another section of Ejepasante and mechanics, this time it's going to lubricants, greases, oils, etc. In this first installment we will see which areas need to grease or lubricate and second types of lubricants used in mountain biking.
try to
therefore give some of advice for almost any type of mountain biking with the exception of carbon, which inevitably have to use very neutral fat or specific for this material, I will review the file a little later, we now focus on those bikes are metallic (mostly) and is today the most widely used aluminum material with steel, but keep in mind that the bike also has a lot of plastic components.
We will try to make a simple classification to do the first thing to be clear is that the bike has two types of components lubricate clearly differentiated: the moving parts or friction, and are not subject to movement or friction, both need the fat, then we'll see why. Within each of these groups in turn we find two types of parts, or rather with the location of them, which can be classified as internal and external parties, as a general rule we use always grease and oil the internal parts or fat, depending on which component to external parties.
On the other hand many times when grease or lubricate the bike we are in doubt about what kind of fat put in each site, the truth is that this has also changed considerably and lubricants found today specific for nearly every bolt of the bicycle, see that it is an exaggeration and that only one type of fat and oil only we will be more than enough and why.
The use of fat has a double meaning, first to avoid burnout, and the second is to prevent oxidation of components, it prevents moisture and air to penetrate the metals producing its so dreaded. The amount of grease to apply to be fair, we should not overdo it or falling short, and tries to cover part of a film of fat or less fat, we need not take half the pot.
internals main oil that you would get red in the Decathlon 9.1 to as an example. As you can see it inside the seat tube, the bottom bracket, full address including the power to where it screws with the handle, the threads which engage the pedals and tilt axes that allow the rear shock and you may also is necessary to grease the rollers inside the hubs. Happens to access some parts that you get is complicated and requires skill, but if we ever grease the bike in full, this is what we must not overlook ever.
There is one exception to this rule, which generally tends to be the core of the cassette, at that point and to avoid dulling will use a thin oil, even motor. For utlimo say that some people have a habit of putting a thin film of grease on the brake and shift cables to make it smoother movement and prevent friction.
Now let's see green where you have to use oil, and we said that we will use only oil on the outside of the bike as a general rule. I put the same bike but green highlighted areas that require oil as you can see almost everything is focused on the transmission and chain. We should not overdo it with too much junk oil or catch them, a small "bath" along the entire chain along with a few drops onto plates and gears, as well as in those joints pequelas diverters will be more than enough. Never use grease on the chain, you will not do more to attract scab and filth.
You will have seen that I also put in green bars and suspension fork damper rod, many tell me that this not be done, but in my experience is desirable to avoid cracking of the seals and the friction of the rods to prevent these work in dry dust and small foreign particles, that if, in this area needed just two or three drops per bar and a pair of compression to be distributed well. I recommend you do this after every cleaning you do to the bike.
One last tip, as you may have noticed we have not put any oil or grease on the brake disc areas, this is so for two reasons The first is that if you do not slow down, and the second is that if you pollute the brake pads with oil or grease, you can not reuse cleaning them because they are very porous and allow great penetration of oil or grease. So keep well away from the disc brakes all that fats and oils are
Finally say that we highly recommend placing a drop of fat in those areas that have bolts or suspicions that may rust or have tendency to do, but always remember that outside parties exposed to air or not to be fat and not to overdo it with oil.
