water effect

What effect does water have on the inside of the frame and parts?

If you turn the bike upside down or remove the seat and turn it upside down, water dots may come out.
Mostly around the seat pillar, around the head, and small holes in the pipes of the frame while driving
seems to come from
The other day, when I removed the wire lead under the bike after cycling in the rain, water came out.

Water in the frame causes rust, but in the case of steel, it is rust on the surface, so there is not much problem.
In the case of aluminum, rust progresses inside, so it is better not to rust if possible.
Especially around the bottom BB, water tends to accumulate, so a method that is resistant to rust is required.

Water entering parts is especially harmful to bearings.
The type called ordinary cup and cone will naturally fall down even if water enters.
It seems that the shield is difficult to enter but difficult to come out, and the amount of grease is originally small, so it seems to be damaged easily.

Pretty bad for wires.
Steel wires rust and become sluggish.
Stainless steel is great for that.
I tried various things when I was a mechanic, but I thought of a way to keep the movement better than normal even if I wash the car every day.
Since it is impossible to completely prevent water, it is also possible to assemble so that the performance does not deteriorate even if water enters.

There is no problem with a little water, but dirty water and snow melting agent water in early spring contain salt.
Not good for bearings. Rather than leaving it as it is, it is better for the bicycle to wash it with clean water.

If it rains during a MTB race, etc., wipe off the mud on the BB, suspension parts, chains, etc.
Moisture in the mud contains fine soil, so it gets inside and becomes like a compound.

If possible, it is better to wash the car with a high pressure washing type with less moisture.
It blows away quickly with pressure and dries quickly.
However, if you don't think about the direction in which the water is poured, it will enter inside, which will have the opposite effect, so be careful.
People who are not used to it may be better to use tap water.
It's best not to use it where you don't need to spray water.

The water hose has a lot of water, so finish it quickly.

When I was a mechanic, I thought it would be better to wash with tap water, but when I tried using high pressure washing
It turned out that it is harder for water to enter than washing from the tap.
In the beginning, I hit random jets, but found that there was a direction, and since then I've been using the high pressure one.
In general, tap water is used due to equipment, but if used well, high-pressure washing can reduce water infiltration.

But either way, water is not good for metal, so you can make a difference by assembling it firmly when assembling.
