Top up/Put Latex on MTB or E-BIKE – TUTORIAL

Tubeless is a great invention but requires a minimum of biker expertise for maintenance and control. Here are some guidelines.


Tubeless continues to save the rides of hundreds of bikers every day, often without anyone noticing. But the latex inside the tire is a liquid and as such it "evaporates"/is absorbed by the rubber or, simply, is dispersed after a few bead breaking/small holes.

HOW TO SOLVE A PUNCTURE WITH TUBELESS

HOW OFTEN SHOULD I TOP UP THE LATEX?

To try to give an approximately correct estimate, I would say that every month you have to check its condition by shaking the rubber and trying to understand if there is still latex inside it: in the warm months it could have already dried out in 1 month while in winter it could even 3 months. In case we have run into punctures and the latex has plugged, the time is reduced.

HOW DO YOU TOP UP?

There are 2 ways, either by removing the tire or by using a syringe and adding the latex directly from the valve.

REMOVING THE TIRE
This method is the most practical and does not require any special tools other than a tire lever. But the drawback is that, by removing the tyre, it may be necessary to use the compressor to avoid not being able to get the tire to heel. You simply have to remove the tire so that you can insert the latex inside. Once the latex has been inserted, close and inflate.

WITHOUT REMOVING THE TIRE
This method has the advantage that the use of the compressor is not necessary. But it requires a small tool to remove the valve ball (see photo below) and a syringe to insert the latex (it is possible to do this even if the latex has a small enough final spout so as not to disperse the latex all outside the valve). The lung is removed so that the latex can be inserted directly from the valve.

HOW MUCH LATEX SHOULD BE PUT INSIDE THE TUBELESS?

Remember to wash the syringe well with water to prevent the latex from clogging the tube.

[email protected] I am passionate about everything that has 2 wheels: in my youth I practiced competitive cycling on the road and on the track with good results. At the age of 18 I moved to cross country competing at national/international level as U23. Once I passed Elite, I made the choice to take things easier from the training point of view, and that's how my love for gravity disciplines was born, training as an FCI MTB instructor and guide. Now I have made my passion my profession by managing 3 MTB centers on the island of Elba (Elba MTB), creating the FANTAmtb and telling in an ironic but professional way, everything that revolves around MTB thanks to 365mountainbike and 365TV (YouTube 'PULITI dentro BIKER fuori').
