TECHNOLOGY:
- Puncture Protection Strip (PPS): an extra layer of handcrafted, unique, highly resistant properties that is placed between the casing and the rubber to reduce the risk of punctures. The tyres are intended for heavy-duty use with a high risk of punctures and are protected with a second PPS layer under the shell.
- Rubber: Challenge's rubbers are made from locally sourced natural rubber in Challenge's own factory in Thailand. Not only is natural rubber more flexible than synthetic rubber, but it also provides much better grip.
- Shell: Challenge casings are made of silk, cotton or polyester. They provide good, long-lasting qualities.
- Tubeless Ready: tyres or casings that do not have an inner tube.
