With this post I do not intend to convince anyone at all, but to demonstrate why the tubels is a practically infallible anti -nching system.
If you are doubting between riding some
Wheels with camera or tubeless system on your mountain bike, here are some accounts reasons about why they are worth the second.
In the first place, it is necessary to indicate that tubess wheels require maintenance. It is minimal and quite economical, but we cannot forget because the liquid that these wheels carry has a certain useful life and it is necessary to renew it.

One of the most reputed manufacturers,
Joe's no Flats, indicates in its products that the tickling fluid must be replaced every, at least three months. This is because the covers perspire through micro-by and therefore the liquid tends to dry.
The tubeless liquid is based on a mixture of ammonia, water and some chemical adhesive such as latex. Each manufacturer has its secret formula, but basically these are the elements used.
It can be done homemade, as you can find in dozens of videos on the Internet, but I have tried myself and the truth is that it does not come out much cheaper than buying a liter in stores.
How the tubeless works
The basis of the operation of this liquid, which rests inside the roof (it must be tubeless ready, as well as the tire), is that at low pressures and with an air escape by a small puncture, the liquid goes To the hole, and helped by its adhesive compound and the pressure leak, seal that area quite safely.
It is true that pressure is lost, but it does not come down from 1bar, so we can finish the route comfortably without getting off the bicycle. If we have a bomb or CO2, it will not mean the smallest problem.
What are the covers and tires "Tubeless Ready"
To convert the wheels of our mountain bike to the tubeless system, we need both tires and the cover to be "TUBELESS READY".
This means that the manufacturer has prepared these components to be able to remove the cameras and be able to use a special tubeless valve. They are valves with detachable howbils, and can be bought in conjunction with the liquid and the tire bottom.
This last element is very important, since the tire must be completely isolated from outside, without air leaks. If the tire bottom is damaged or we have not placed the new one, we will know when we introduce the liquid and swell the wheel.
If there are leaks, the liquid will make us chivato (it is quite scandalous).
Do tubeless fluid seal all punctures?
Well no. Unfortunately it is not reliable to 100%, so it is recommended to carry a camera in case the tubeless does not exercise its function.
And when does this happen? Well, in cases of rajas on the deck. A hole of more than 3mm will not be sealed by the fluid, so a really effective, but not valid puncture repair system is usually used if we find rajas or major holes of those 3mm.
In this dramatic case, a camera must be used. The tubess and liquid valve must be removed, and set up the camera.

Yes there is a small trick for those rajas, although I have never been able to verify its reliability. It consists of putting inside the roof, swimming between the tickling fluid, small shoe cord pieces, about 5mm long.
The sector gurus comment that in this case rajas of up to 3mm would be sealed, without a need, even older. I insist, they are popular inventions and theories, not backed more than by some personal experiences of a few.
The great advantage of tubeless: weight reduction
While it is true that as an anti -infinite system it is great, there were already similar systems, such as cameras with liquid inside.
However, the fact of being able to eliminate the chamber from the equation makes us save about 150 grams of weight on our bicycle, a reduction that if we try to apply in handlebars, shell or other components, it would be very expensive.
Rolling to low pressures
Another advantage is the possibility of being able to roll at low pressures without fear of the dreaded prick for “snake bites” of the camera. Rolling at low pressures, that is, 1.4 bar for example, it is something very common in our day.
The wide covers, of more than 2.2 ”, give us a great ball, and with pressures of 1.4 to 1.5 bar we have better traction rising, and greater security down and in the passage through curve, as well as greater comfort In very stone areas.
Yes, we must take into account the weight of the bici-cyclist ensemble when choosing pressures, but of course that with tubeless wheels we can lower in any case of the 2 bar without any fear of punctures or decalon.
At this point it is worth highlighting a relatively new product in the market: Panzer. We talk about a kind of 'pool churro' of foam, which is placed inside the roof, and that avoids not only that we disagree, but also that we can hit the tire in case of a sudden loss of pressure by a generous puncture.
These systems have a great disadvantage, and they absorb tubeless fluid. If in a normal tubess assembly we must replace the 60-70 ml of tickling fluid (we talk about 29 ”) every three months, using these Panzer type protections we must replace the liquid in the middle of the time.
How much does it cost to move on tubess wheels?
If your bike is not relatively modern (we are talking about 2017 onwards), a tubeless kit can be purchased for about € 30, although you should also change the covers since the Ready tubels are less porous and therefore suitable for this anti -infinite system.
TUBELESS ROUTES ON THE ROAD
This is another song. We talk about pressures of 6-7 even 8 bar, and therefore, too much force to support at the pressure leakage point for the liquid.
For pressures up to 5 bar is more than proven that Tubeless is a large anti -infinance system, especially before very finite holes, caused by a small nail, or small crystals.
[IRP posts = "1071" name = "wide tires; a new trend in road cycling"]
We would be talking in this case of 28 or 30mm covers. For 25 or even 23mm covers. In road cycling, Tubeless is really very green and still needs evolution, since 7-9 bar is not effective.
In conclusion, I strongly recommend the use of tubess wheels in Mountain Bike. But although I have been using it for several years and I am more than satisfied, I never go out with without a camera in the drum of the tools in case.
