FAQ

LIGHT AND ROBUST, HOW IS THAT POSSIBLE?

Due to innovative processing of a special material Tubolitos are not only lighter but also more robust than classic tubes made of rubber.

What do you mean by twice as robust?

To measure the puncture resistance of a bike tube the needle penetration test is an important parameter. It measures the force needed to puncture a tube with a test mandrel. This test indicates: compared to standard rubber tubes twice as much force is needed to puncture a tube of the Tubo-MTB series.

Can Tubolitos be patched?

Yes, with the Tubo-Flix-Kit developd by us a Tubolito can be easily patched.

For which bikes/tyres do you have suitable products?

To see all our product range please visit the “products” section on our homepage. However, we are constantly testing new ideas and innovations. As soon as a new product is available, we will keep you informed on our homepage and on our social media channels.

Can Tubolitos be used with sealant or repair sprays?

Yes, we performed tests with different products. Following products seal Tubolitos:

Sealant: Oko Puncture free Bike

Repair Spray: Nigrin Reifendicht; Vittoria Pitstop Super Magnum; Tip Top Pannenspray; Güp Kwiki

How about air retention of Tubolitos?

As the graph indicates, Tubolitos do have a similar characteristics concerning air retention as rubber tubes.

How resistant are Tubolitos against "snake bites"?

Regarding snake bites Tubolitos do have similar characteristics as rubber tubes.

Why are Tubolitos orange?

We wanted to also optically highlight the innovative nature of Tubolitos and we really liked orange in this context! Furthermore, the covering paint of the tube does also bring a useful effect with it as it helps to protect the tubes against environmental influences such as sunlight. Thus: orange is the new black!

What's the difference between Tubo and S-Tubo products?

The “S” stands for spare, referring to the ideal spare tube. Due to reduced thickness S-Tubos are not only extremely light but also very small. Furthermore S-Tubo-MTBs do have a removable valve so they do fit in every pocket, how small it may be.

Are Tubolitos compatible with valve extensions?

Yes, we performed tests with “Topeak Presta Valve Extender series” valve extensions and our valves are completely tight. Remark: The valve cores of all our products are glued in and therefore not removable.

Are Tubolitos ready for rim brakes? What about heat resistance while braking?

While our road products are also made for rim brakes, the tubes for MTB can only be used with disk brakes. This is due to the different processing of the material.

Our road products do comply with the test DIN4210 (15 minutes of braking with maximum 10×10 seconds interruption) with aluminium and carbon rims.

Doing a disruptive test, meaning braking as long as the product is defect, Tubolitos do not lose the air explosive such as butyl products, but slowly over several minutes.

How about the rolling resistance of Tubolitos?

We had our products tested by an independent body. The graphics listed below show the results.

How much pressure can Tubolitos be used with?

The maximum and minimum air pressure are basically determined by the tyre. Please check the indications of your tyre!

Please note that not mounted Tubolitos are not supposed to be inflated with more than 0,5bar/7psi. Otherwise they will be deformed and can get defective.

Can Tubolitos be dismounted and remounted into another wheel?

As long as the dimensions of the the wheel (wheel diameter and width) are the same, this can be done without problems.

Can Tubolitos be inflated with CO2 cartridges?

Yes. However, as for butyl tubes, CO2 does not stay as long in the tube as air, meaning that reinflating will be necessary earlier.

How environmentally sustainable is the production of Tubolitos?

For the production of the raw material necessary for a 85 gram Tubo-MTB-29” about 7MJ energy are needed and about 0,3-0,33 kg CO2 are emitted. In comparison, the production of the raw material necessary for a 200 grams standard tube made of butyl rubber 22 MJ energy are needed and about 1,26-1-33kg CO2 are emitted. The graphic below illustrates that also the water needed to produce the raw material for Tubolitos is much less than the water needed to produce the raw materials of other tubes.
