If you like a fast ride in light terrains with a hard surface, then we recommend a Zefyros Top Design mountain bike tire. For the new season, the tire has been innovated based on the knowledge of our riders. Zefyros is a MTB tire with fine and low treads. These ensure low rolling resistance and a fast and safe driving experience. The tire has a Kevlar bead and the patented Textreme technology, which increases the resistance to lateral puncture. Construction Tubeless Supra:Frame: 127 TPI, drum technology (OLT)Sidewall: Skinwall (SW)Aramid (A) + sealing bead protectionCan be used as a tubeless tire by using a special mounting kit. Increased riding comfort, reduced rolling resistance, very stable and safe riding in difficult terrains. Effective protection and elimination of the sidewall defects and punctures (Snake Bite).Technology Textra+:Very dense and extremely strong rubberized fabric placed on the side of the tire and around the entire bead. Its excellent elasticity and almost negligible weight maintain the excellent driving characteristics of the Tubeless Supra tire. At the same time, Textra multiplies the tire’s resistance to side punctures with minimal impact on its weight.Tires with this protection are designed for very difficult racing terrains, guaranteeing maximum reliability while maintaining excellent driving parameters.Mixture CRX (Carbon Race Extreme Light):This mixture contains active carbon black, which increases structural strength, durability, and provides excellent adhesion and grip properties with low rolling resistance. The density is 1.02 g / cm3. Due to its properties, it is recommended primarily for racing purposes.
