Race-Series Vulcanized Tubeless Ready with nylon carcass
Vulcanized tires made of natural rubber score with a very good price-performance ratio and high durability at the expense of comfort and performance.Nylon is a braided carcass that is essentially available in three thread sizes - 33, 60 and 120 TPI (threads per inch). and wrapped around a wire or the aramid bead. The nylon braid is dipped in a bath of butyl rubber and then calendered (squeezed) between large steel rollers to create the finished carcass. In bicycle tires, nylon offers a first-class cost-benefit ratio due to its low price and comparatively simple processing.
Vulcanized synthetic rubber
Synthetic rubber is boiled and hardened to combine high durability with good driving characteristics. The result is Challenge's Vulcanized Clincher: smooth-running tires with high grip and good comfort at an affordable price.
Puncture Protection System (PPS)
Additional layers of high-strength fabric between the carcass and tire to reduce the risk of punctures.
