Challenge tyres should not be mounted on wheels that do not meet ETRTO and ISO standards. Non-compliant wheels could cut through the sidewall above the bead, causing the tyre to burst and possibly injuring the rider.
Handmade tires combine essential characteristics such as natural materials, ultra-fine carcasses and a flat, flexible shape to achieve top values in comfort and rolling efficiency.
Natural rubber - SmartPlus hardness level
Tyres made of natural rubber earn particularly high marks in terms of performance, comfort and control and boast a notably long service life. They are available in various degrees of hardness, with SmartPlus being a harder natural rubber compound designed for high durability.
The SuperPoly carcass is made of polyester, which is characterised by its durability and waterproof aspects, while at the same possessing remarkable flexibility. The TPI number is significantly higher than for other carcasses, so the material is finer and therefore more flexible.
Carcass with double layer of SuperPoly for increased durability and stability.
The Puncture Protection System (PPS) Ganzo is a tyre insert strip made of flexible, tightly woven multi-component fabric, which is used between the tread and the carcass of the tyre.
