Guaranteed good graveln!

Designed to fit in any small bag, the lightweight Tubolito X-Tubo CX / Gravel-All is the ideal spare tube for gravel tires with 30mm-50mm tire width due to its small pack size. Equipped with the same robustness as standard butyl tubes, it is not only a reliable savior in an emergency, but can also be used without hesitation in everyday use. The X-Tubo-CX/Gravel-All is equipped with Tubolito's proprietary X-Tubo technology for maximum puncture protection. This is extremely resistant to thorns, nails and shards.

X-Tubo

In developing the X-Tubo technology, Tubolito had a goal that was as clear as it was ambitious: to produce a bicycle inner tube that could no longer be flattened. To achieve this, tubes were made from different materials using different processes. The prototypes were subjected to a wide variety of tests. The approach was to test in a very practical way. The developers at Tubolito drove over thorn bushes, scattered broken glass and crossed them, and drove over a specially developed nail ramp. In this way, they approached it step by step until they themselves were convinced that they had found a product that would make punctures impossible in everyday life.

Designed, developed and manufactured in Europe

Tubolito hoses made of the high-tech material thermoplastic can withstand forces two times higher than standard hoses. The material can be stretched more than four times, providing maximum protection from a puncture.

Tubolito hoses under test

A 0.75 mm test mandrel travels at a defined speed through a pre-drilled hole in the casing. Tire pressure is 2.0 bar. The force and the distance to the tire burst are recorded. Tubolito is clearly convincing here: Puncture safety is twice as high as with standard tubes in terms of puncture.
