This tire offers high performance on all types of roads and trails, and maintains excellent performance at various inflation levels. The smooth tread reduces rolling resistance while the ZSG natural rubber compound ensures consistent performance even in varying temperatures.

Please note that the actual width of the tire may vary up to 6mm or more depending on your inner rim width and inflation pressure. Also, this tire is tubeless compatible and can handle up to 60 psi.
