E-Bike ready 25
In standard pedelecs that have motor assist up to 25 km/h, there is no legal requirement for a special tire. But even with these bikes, loads and average speeds are higher than in regular bikes, therefore we recommend only certain tires as “E-Bike Ready 25”.
Tubeless ready
Performance. TL ready. Tubeless for Performance versions. Extra-strong bead cores, with rubber reinforced sidewalls.
EVO Line

TPI (EPI) - the density of the tire's skeleton fibres. The higher the TPI value, the more flexible the tire will be.
Kevlar tire - foot made of Kevlar fibres. The tire can be folded, so it is more practical when moving or storing. It is characterized by a lower weight compared to wire casings and a higher resistance to puncture.
Wire tire - bead made of wire. The tire is inflexible, it is heavier than Kevlar.
