The cycling tube is a combination of large volume and low weight. Cyclists will certainly appreciate its high reliability. Each tube is inflated at the factory for 24 hours and tested for cracks. Not only the quality of the admixtures, but also the purity of the mixture is important for the quality of the tube. Therefore, these tubes retain air significantly longer than others.

The tube is extremely flexible and fits several dimensions of tires. For this reason, it is also called "Group Tube". The tube 19A fits into tire sizes from 27.5 "to 29" and widths from 40 mm to 62 mm.

A special devulcanization process was used in the production. Thanks to this, it is possible to use recycled material without loss of quality in the production of new tubes.
